Sorry Russell… The Jaeger-LeCoultre Master Control Chronometre Date Power Reserve is the way to go

For Zach, his favourite of the group has to be the Jaeger-LeCoultre Master Control Chronometre Date Power Reserve. Here's why...

Hands On With The Jaeger-LeCoultre Master Control Chronometre Date Power Reserve

Jaeger-LeCoultre’s new Master Control Chronometre collection is a hit. Now we put the Date Power Reserve model under the microscope… What We Love Great integrated bracelet design, & a first for Jaeger-LeCoultre Super comfortable on the wrist  Bridges both sports and dress watch genres easily What We Don’t No lume, so a better watch for day wear vs an all-around sports watch The bezel could be larger or have more detailing for greater balance Need a corrector tool to change the date, so it isn’t easy to do when out and about. Overall Rating: 9.25 / 10 Value for Money: 9/10 Wearability: 9.5/10 Design: 9/10 Build Quality: 9.5/10 Mario has had his say on the new Jaeger-LeCoultre Master Control Chronometre Date, but now it’s my turn, and for this review, I’m getting hands-on with the Master Control Chronometre Date Power Reserve. Yes, the name is a mouthful, but that is ok, I’ll forgive Jaeger-LeCoultre as this is (spoiler alert) a fantastic watch that I really had a hard time faulting. Since seeing the full collection first-hand at Watches & Wonders this year, I had been keen on trying them for a longer-term review. I do love the rose gold variants, but the sensible part of me thought it best to give the steel version a try, as this is probably the more everyday-wearing watch, and design-wise, sits nicely between the date model and the perpetual calendar. First Impressions I’ll say this. My first impressions of the Jaeger-LeCoultre Master Control Chronomet...

Introducing: Panerai’s Luminor Marina PAM01707 Is All Classic Everything, Except For The High-Tech Composite Case

What We Know As one of the more recognisable watch designs, period, the current Panerai Luminor shape has been rendered in many different materials since the 1955 introduction of the crown protection device. This latest take, the Luminor Marina PAM01707, is cased in Carbotech, a composite material combining carbon fibre sheets and polyether ether ketone, resulting in excellent anti-corrosion properties and lightness. Though Panerai’s products now comfortably sit in the luxury watchmaking category, it hasn't stopped them from using avant-garde materials suited to the original intent of their designs. Measuring 44mm across and 14.5mm thick, the PAM01707 has all the hallmarks of a classic Panerai, with its cushion-shaped mid-case sandwiched by a round, striated Carbotech bezel and a DLC-treated titanium caseback. The signature bridge, which spans the right-hand side of the case and protects and locks the crown, is also rendered in carbon, matching the uneven, textured finish of the rest of the case. This sanga-based analogy can be expanded on for the dial, another Panerai hallmark. The textured, matte top plate features cut-outs for the stick indices and Arabic numerals at the cardinal points, as well as the small seconds indicator at 9 o’clock, allowing the fauxtinated Super-LumiNova bottom layer to shine through. Here pictured on brown calf leather, Panerai also includes an “Officine Panerai”-branded black rubber strap so you can actually take the watch swimming, th...

An Ideal Blend Of Old And New: The Panerai Luminor Marina PAM01707 In Carbotech

Panerai combines a high-tech carbon-composite case with familiar vintage-inspired details in the new Luminor Marina PAM01707. The watch uses the brand’s proprietary Carbotech material for its 44mm cushion case. Paired with an automatic movement and 300m water resistance, it remains every bit the capable tool watch expected from the Luminor Marina family. What makes this […] Visit An Ideal Blend Of Old And New: The Panerai Luminor Marina PAM01707 In Carbotech to read the full article.

Introducing - The Panerai Luminor Marina PAM01707 in Lightweight Carbotech

Panerai expands the use of advanced materials across its collections and reveals the new Luminor Marina PAM01707. The overall design remains unmistakably that of the classic Luminor, with the crown-protecting bridge, sandwich dial and 44mm proportions, but the latest addition pairs these familiar elements with a full Carbotech case. This lighter, highly corrosion-resistant version of […]

Hands-On: A Triple Review Of The Jaeger-LeCoultre Master Control Chronomètre Collection

We're a few months removed from Watches & Wonders, which gives us some clarity about what was buzz, what was hype, what fell off the wish lists, and what will be a long-term winner. It's looking like Jaeger-LeCoultre had one of the best releases of the fair with the Master Control Chronomètre series. The Master Control line has largely been a dressy take on traditional design cues for a brand people usually think of first for its Reverso. But now, JLC has shown that Master Control can do more. More than just a new case and bracelet, all watches are in-house chronometer-certified 4Hz, 70-hour power reserve movements (COSC does the certification) with a new High Precision Guarantee (HPG) seal, which supplants the former 1000 Hours Control. That new HPG seal means that the brand trials cased watches on four daily-wear specific issues—shocks, positions, altitude, and temperature—over three days, while guaranteeing eight traditional techniques of quality aesthetic finishing. The watches I photographed were brand new and wrapped in plastic, so you have to look past a bit of that to see the quality, but it certainly is there in person. Now with three models in steel and rose gold, with five SKUs (one watch only comes in steel and not gold), measuring 38mm by 8.4mm or 39mm or 9.2mm with 50m of water resistance, the new line brings a lot to the table. Inspired by the brand's Master Mariner Chronomètre line, launched in 1973 as their offering for an integrated bracelet (or adj...

Jaeger‑LeCoultre reshapes the Master Control line with three new Chronometre models in two materials. The collection takes inspiration from the integrated case and bracelet first seen on the Master Mariner Chronomètre in 1973. This time, the execution feels thoroughly modern and far more refined. The lineup includes the 38mm time-and-date model, a 39mm version with […] Visit Introducing: The Jaeger-LeCoultre Master Control Chronometre Collection to read the full article.
