Hands-On With Longines Master Collection Chrono Moonphase: A Complicated Classic, Refined

I’ve had the chance to take the newly redesigned Longines Master Collection Chrono Moonphase for review to see how the subtle refinements elevate this complicated favourite! What We Love Refined, less cluttered dial design Exceptional complications for the price Beautifully matched blue leather strap What We Don’t Limited 30m water resistance Substantial thickness for smaller wrists Busy display may not be to everyone’s liking. Overall Rating: 8.9 / 10 Value For Money: 9/10 Design: 9/10 Wearability: 9/10 Build Quality: 8.5/10 There are few watches that bring together Longines’ classical design language and mechanical expertise as completely as the Master Collection Chrono Moonphase. This is one of my favourite Longines models, and I have finally had the opportunity to review the latest evolution of one of the brand’s most iconic timepieces. View this post on Instagram A post shared by Watch Advice (@watchadvice) Longines first introduced the Master Collection in 2005 to showcase its traditional watchmaking expertise through an entirely mechanical collection. It was created as a meeting point between the brand’s classical elegance and its ability to produce increasingly complicated mechanical timepieces. This distinguished the Master Collection from Longines’ sportier models through its more traditional dial designs, decorative finishing, and mechanical complications. The 1911 Longines pocket watch serves as the inspiration behind the aesthetics of the Chr...

eBay Finds: Great Vintage Watches from Seiko, Hamilton, Zodiac, and More!

eBay Finds is back! This bi-weekly installment will feature a selection of watches currently listed on eBay that have caught the eye of editor Christoph McNeil (@vintagediver). If you come across any hidden gems on the ‘Bay drop us a note at info@wornandwound.com for potential inclusion. Vintage CompuChron LED You gotta love a good vintage LED, especially when it comes with the box and papers! This example is a nice, chunky CompuChron in stainless steel. The space-age steel case is excellent with sharp edges and original mix of brushed and polished finishes. The LED screen looks nice and clear, and the printed CompuChron logo is crisp. The watch comes on the correct and original integrated steel bracelet with a signed buckle. Best of all it comes with the original box and instruction manual, which is always handy. The watch runs and all the LED segments light up. Really fun piece that’s in amazing condition.  View auction here Vintage Seiko Seikomatic  Here is a sweet vintage Seiko Seikomatic from 1966. Seller doesn’t state, but this should be a 38mm case size. The case looks unpolished with sharp edges on the cool, angular lugs. The classic Seiko silver dial is clean, with nice clear writing and applied steel baton markers. Steel dauphine hands and an unusual date at 3 o’clock with day at 6 o’clock complete the look. The small crown is recessed at 4 o’clock. The serial number on the caseback dates this one to January 1966. The automatic movement is clean and...

Introducing: Seiko Prospex 1965 Heritage Diver's Watch HBC011 Hodinkee
Seiko Prospex 1965 Heritage Diver's Aug 28, 2026

Introducing: Seiko Prospex 1965 Heritage Diver's Watch HBC011

What We Know Seiko has launched a new version of their popular vintage-inspired 1965 Heritage Diver, with a dial and color palette chosen by you. Okay, well, maybe not you directly, but through a fan-selection process that Seiko launched last year to mark the 60th anniversary of the original 62MAS diver. Seiko fans were presented with four variants of a watch that would eventually reach production, each inspired by a different tone and color the ocean can take on over the course of a day. In the end, the winner of last summer's campaign was this "Daytime Blue" color, which evokes the clear blue waters you'll find in tropical locales where the water is clear and the sun is shining. Other options included a bright yellow, deep green, and orange-y red. It's not wholly surprising that the blue dial would have won in a public ballot, but each is compelling, and I'll be curious to see whether Seiko, having developed and shown off the full range, ever chooses to release any of the other colors. The watch itself is a familiar one. The HBC011 shares a spec sheet with the enthusiast-favorite (and James') favorite SPB lineup of dive watches, specifically with the '20MAS' generation released in 2024, which brought with it a host of quality-of-life improvements, including a refined case and new movement. That case, which Seiko claims to be 40mm wide, 13mm thick, and 46.6mm lug-to-lug (and which James measured at 40.2mm wide, 13.4mm thick, and 46.6mm lug-to-lug in his Hands-On), is agai...

Introducing: Studio Underd0g 02Series "Mantis" Hodinkee
Studio Underd0g 02Series Mantis What We Aug 28, 2026

Introducing: Studio Underd0g 02Series "Mantis"

What We Know Not even two months on from the initial launch of the updated 02Series Gen 2, Studio Underd0g is jumping headfirst back into limited editions with the Special Edition 02Series Mantis. The headline here is a bright green, full-lume dial, which Studio Underd0g claims is the brightest to ever grace a watch from the brand, but it's also worth reiterating some of the changes that the brand brought to this watch earlier in the summer. The biggest change separating the 02Series Gen 1 and Gen 2 is the new case used for the latter. Upsized by half a millimeter to 37.5mm, the case has also been thinned out and now measures just 11.5mm rather than 12mm, and a full 2.1mm of that comes from the domed sapphire crystal. With lug-to-lug holding steady at 46mm, the updated case finds itself squarely in the Goldilocks zone for many collectors. There are also some meaningful technical updates in the new watch. Tolerances are tighter, and the SW210 movement has been replaced by the SW200-2 M (modified to remove the automatic winding system), which brings with it an accuracy of ±7 seconds per day and 63 hours of power reserve. The whole watch is assembled in-house at the D0ghouse, Studio Underd0g's newly established workshop, and is an evolution of the Horologium. All that said, the real reason to buy this watch is the dial. Like most watches from Studio Underd0g, the 02Series Mantis uses a sapphire sandwich dial construction, with a transparent sapphire disc printed with the min...

Go Big or Go Home: Fears Adds Its First High Complication with a QP Worn & Wound

Go Big or Go Home: Fears Adds Its First High Complication with a QP

Fears has decided to add its first high complication by tackling one of the most complex of them all: the perpetual calendar. Charting new territory seems like just the right way to celebrate the brand’s 10th anniversary since its renaissance in 2016. The introduction of a QP to the flagship Brunswick line isn’t the only headline. The collection gets a new case architecture with wide polished bevels making it the thinnest Brunswick watch in the line at 9.4mm. The Brunswick has been a defining collection for Fears since its introduction in 2017, marking the first mechanical line of the modern era. Yet, the collection is also an homage to the brand’s past with a vintage-inspired cushion shape case, onion crown, and signature sector dial. The design mixes these aesthetics with distinct typography and numerals derived from a piece from the brand’s archives. It only feels fitting that this collection would serve as the foundation for Fears’ first high complication in 180 years.Even with the addition of day, date, month, year, and leap year indications that make up a perpetual calendar, Fears has managed to keep the Brunswick QP compact at just 39mm. When it comes to high complications, the composition of the movement is usually the main limiting factor when it comes to sizing. Here, we can thank the Dubois Depraz perpetual calendar module, atop a hand-finished Sellita SW300 as its base movement. This caliber has been modified specifically for this watch, giving it its...

Hands On: Patek Philippe In-Line Perpetual Ref. 5236P-011 “Gradient Silver” SJX Watches
Patek Philippe In-Line Perpetual Ref 5236P-011 Aug 28, 2026

Hands On: Patek Philippe In-Line Perpetual Ref. 5236P-011 “Gradient Silver”

Patek Philippe’s latest take on its flagship perpetual calendar is the In-Line Perpetual Calendar ref. 5236P-011 with a “gradient silver” dial. Though a cosmetic update to a model that’s only been in production since 2021, the new dial is unexpectedly appealing, giving the watch a striking different feel from its predecessors. Patek Philippe’s most advanced calendar movement, the cal. 31-260 PS QL inside the ref. 5236P is a latest-generation base movement matched with a newly-developed perpetual calendar module. The movement is now in the third generation of the reference; the ref. 5236P-011 replaces the ref. 5236P-010 with a “rose gilt” dial that was only in the catalogue for two years. Initial thoughts The ref. 5236P-011 is a new face for an existing model. Though the design remains unchanged, the dial finish that darkens towards the edges gives it a more modern feel. The composite strap adds to the modern feel, though the strap might be a bit too sporty for the watch. Paradoxically, the smoked dial finish also brings to mind aged or “tropical” dials on vintage watches. The rest of the watch stays the same, but it’s a good one. The ref. 5236P is an impressive watch in both technical and physical terms – it’s the brand’s most advanced perpetual calendar and also its largest. The size and weight are reassuring, and actually bring to mind complicated models from a rival brand from Germany. But the case is made up of lots of flat surfaces and entir...

Introducing: Noah x Timex MK1 Anchor (Live Pics)

What We Know This week, Noah, the New York City–based menswear brand that has made a name for itself by blending modern streetwear aesthetics with classic Ivy style, has dropped yet another in their series of highly sought-after limited-edition collaborations with Timex. But this time, instead of evoking classic dress watches, they've opted to move in a sportier direction, reimagining Timex's MK1 field watch into a fun everyday watch. The new watch uses the 36mm version of Timex's MK1 field watch as a base, but swaps the military-inspired dial used in the majority of that line for a nautical-inspired silver opaline dial. The Timex logo stays put near twelve o'clock, with the cursive Noah wordmark joining it just below.  A printed minute track with lumed pips runs around the outside of the dial, and applied markers, alternating between Breguet numerals for the even numerals and dauphine-shaped markers — which mirror the lumed dauphine hands — representing the odd. The small seconds hand brings with it the most significant aesthetic choice on the watch. A red anchor, surrounded by a black railroad seconds track, backs the small seconds subdial and shouts on a dial that otherwise hums. The watch comes with two strap options, each made of a double layer of woven nylon, and fitted with quick-release spring bars. The first of these, and the one more prominently featured in the brand's marketing materials, is a red and navy double stripe, but the watch also comes with a so...

Anordain’s New Model 1 Combines Porcelain Dial and Custom Font SJX Watches

Anordain’s New Model 1 Combines Porcelain Dial and Custom Font

Best known for its affordable watches with fired enamel dials, Anordain is diversifying its offerings with the Model 1 Porcelain. Sporting a traditional porcelain dial, the new Model 1 showcases a brand-new, custom font that’s a twist on the traditional Breguet style, reflecting the brand’s focus on the finer details of design. Beyond a new design direction for the Scotland-based Anordain, the Model 1 is also represents a scaling up of its business. While the porcelain dial is made the old fashion way – painted by hand with a clay-based mixture – it can be produced at a higher rate than Anordain’s enamel dials, making the new Model 1 accessible both in terms of price and availability. Initial thoughts The Model 1 Porcelain is interesting from a business perspective. It underlines Anordain’s growth, as well as the brand’s strategy for dealing with its growth. Scaling up production sizeably while still preserving its speciality of traditional, artisanal-type dials is a prudent approach that maintains the brand’s identity. The Model 1 Porcelain, however, is not an industrial product. Rather, it retains the quirky character typical of Anordain’s watches. The watch is still typical Anordain with its clean design and thoughtful details. The dial and typography are appealing, especially with accents like the five-minute numerals and railway-like minute scale. The seemingly mismatched hands leave me with mixed feelings, but the whole is still attractive. The opti...

Introducing: Straum Expedition

What We Know Straum has launched a new take on their integrated bracelet sports watch this week, shifting the focus from evoking nature to getting out and exploring. Fittingly named, the Expedition is the first watch in a new collection which Straum is calling "Built For". This will stand as a second pillar in the brand's offering, alongside the "Inspired By" collection, under which umbrella all the brand's previous releases fall. The most obvious visual cue that something here has changed is the redesigned dial, which swaps the deeply textured, colorful approach of previous Straum releases for a much more utilitarian vocabulary. With bright orange accents, huge amounts of lume, and subtly grained but largely flat dials, the emphasis is less on pure aesthetic appeal and more on legibility and practicality. The same approach has been taken with the case, which has been redesigned, but again, in largely subtle ways. The Grade 5 titanium case — which measures 38.2mm across, 45.7mm lug-to-lug, and is 11mm thick — has been reworked with broader case flanks, a stepped bezel, and a significantly enlarged screw-down crown meant to be usable in the cold or with gloves on. All together, the Expedition is decidedly new, but still clearly and recognizably a Straum. By default, the new watch comes fitted with a black FKM strap, though a new fully Grade 5 titanium case is also available for a modest upcharge, and since the watch uses Straum's strap system, any pre-existing straps an...

Dispatch: Diving With Force Blue And Luminox For Reef Restoration In Miami

Luminox is honoring its partnership with Force Blue by releasing a new Pacific Diver reference designed around the pair's shared mission to protect and rehabilitate the world's oceans. Luminox has a long history of working with branches of the US Military since their founding in 1989, but their relationship with Force Blue is a bit different. To better understand their mission and get a first look at a new watch built around the partnership, I hopped on a plane down to Miami with fins and mask in hand, ready to dive with the team. Many brands claim working relationships with military outfits, each with varying degrees of formality. Whether it's a licensed relationship to use military trademarks, or even individual service members using their personal watches, the link between a brand and the act of service can be difficult to judge at a glance. For Luminox, that connection was baked in from the get-go. In 1992, founder Barry Cohen worked with Assistant Research, Development, Test and Evaluation (RDT&E;) Officer Nick North to develop a watch specifically for the Navy SEALs using their tritium tube-based Luminox Light Technology (LLT). The Navy SEAL watch was the first stone in what would become a broad foundation of work with special forces and law enforcement groups worldwide. It's a foundation that Mondain would continue to lean on after acquiring a stake in the brand in 2006 and full ownership in 2016. Today, Luminox maintains a licensing relationship with the US Navy SEA...

Introducing: Ming's New 57.05 'Comet' Worldtime Is Out Of This World Innovation

What We Know It feels like Ming has another hit on its hands here. The new 57.05 "Comet" immediately looked like a cool watch before I even looked at the press release, but once you dig into the specifics, it's pretty impressive, with all the usual Ming flair to boot. That means, yes, there's a pretty cool dial (that has a touch of vintage inspiration). There's an intensely stylized case. There's lume used aplenty (and creatively), and yes, there's innovation in a new patent-pending daylight saving time (DST) world time adjustment system. Let's start from the outside and work our way in. The 316L stainless steel case measures 40mm by 10.3mm with a 47.8mm lug-to-lug. This is a part of Ming's 57 Series design language, so it's got triple-stepped lugs (requiring nine individual components for the lug construction). The next step is the world time bezel. That's where the magic really starts. With a normal 24-hour world time display, you can get by just fine. Yes, not all DST adjustments happen at the same time (if they happen at all), but adjusting for any of them is a problem. Ming has arranged all cities with DST on the outer bezel; non-DST cities are on the inner bezel. You can rotate the outer bezel one click (15º) to move only the DST cities forward by one hour against the 24-hour scale. The bezel will stay fixed in either position, but if you're trying to figure out whether or not DST is engaged or not, you can just look at the small aperture between eight and nine on t...
