INTRODUCING: The IWC Portugieser Automatic 40, a new contender for the ultimate ‘one watch’

The story of the Portugieser begins with two businessmen from, you guessed it, Portugal. They went to IWC asking for a watch as accurate as a marine chronometer but could be worn on the wrist, something that hadn’t been done before by the brand. The only way the Schaffhausen-based manufacturer could meet the brief was … ContinuedThe post INTRODUCING: The IWC Portugieser Automatic 40, a new contender for the ultimate ‘one watch’ appeared first on Time+Tide Watches.

Grand Seiko ups the ante – on itself – with the SLGH002, where classic meets cutting edge

Seiko is a brand that is well accustomed to competing with itself. Both to raise the bar for the brand’s watches, and for the betterment of the global watch industry. From the revolution of bringing quartz-powered movements to the masses, to embarrassing the Swiss at their own Chronometer Trials, the intrepid Japanese pioneers can seem … ContinuedThe post Grand Seiko ups the ante – on itself – with the SLGH002, where classic meets cutting edge appeared first on Time+Tide Watches.

Hands-On: Ulysse Nardin Diver X Cape Horn and Nemo Point

Dive watches priced below US$10,000 are one of the saturated and competitive segments in watchmaking. The category is dominated by two dive watch icons, the Rolex Submariner and the Omega Seamaster, both of which set the bar high with high-spec, in-house escapements equipped with high-tech hairsprings and next-level chronometer certifications. Ulysse Nardin smartly steered away from the conventional dive-watch look with last year’s new Diver X. Created to mark the brand’s newly-forged partnership with Vendée Globe, a non-stop solo yacht race around the globe, the Diver X Cape Horn and Diver X Nemo Point are a contemporary take on the standard Diver Chronometer 44mm, dressed up in new materials and colours but retaining the same basic specs, namely a 300 m rating and an in-house movement with a proprietary escapement. The Diver X Cape Horn Dubbed the “Everest of the Seas” because of its reputation as the toughest sailing competition in the world, the Vendée Globe is such an arduous journey that the eight races since 1989 have claimed three lives. Competitors have to travel over 40,000 km, a round-the-world trip that takes between two to four months. Unsurprisingly, the twin Diver X editions are aggressively styled and technically robust. Form and function Each named after key points along the Vendée Globe route, the Cape Horn and Nemo Point have the longstanding, symmetrical layout of a Ulysse Nardin diver’s watch – originally inspired by the dial of the br...

Omega Constellation Manhattan: An Overlooked Masterpiece Of Design

As a fan of the classic 1950s and 1960s Omega Constellations, Colin Smith had always dismissed Omega’s 1982 reworking of its flagship model, known as the Constellation Manhattan, as something of an aberration from the “true” Constellation concept. His “road to Damascus” moment occurred recently when he saw a 36 mm black-dial co-axial chronometer on display at an Omega dealer in Bordeaux.

TAG Heuer Introduces the Carrera Heuer 02T Cortina Edition

Launched in 2016, the TAG Heuer Carrera Heuer 02T remains the most affordable Swiss-made chronograph with touribllon, starting at just US$17,000. Despite the price, the Calibre Heuer 02T is an in-house movement that’s automatic, COSC-certified, and equipped with a lightweight flying tourbillon that has a carbon composite upper carriage and titanium base. The latest variant of the affordable “grand” complication is a limited edition made for Singapore retailer Cortina Watch. Dressed in orange and back, the Carrera Heuer 02T Cortina Edition is being offered only online, via the retailer’s website. As with the standard model, the case measures 45mm wide and 16.4mm high. It features the modular construction that characterises the Carrera line. The case middle is black-coated titanium paired with a black ceramic bezel, while the lugs, pushers and crown are steel. The dial is semi-skeletonised to reveal the grey, sandblasted base plate of the movement. Orange accents are applied to the dial and bezel, including the chronograph hands, and even the carbon composite upper cage of the tourbillon, creating a striking contrast with the black components. Mechanically the movement is identical to the standard Heuer 02T. Based on the CH-80 chronograph movement, it’s equipped with a column wheel and vertical clutch for the chronograph. And it has a 65-hour power reserve, with the balance running at a frequency of 4Hz. Key facts and price TAG Heuer Carrera Heuer 02T Cortina Edi...

RECOMMENDED READING: Just what is the Patek Philippe Seal? 

There are few things that high-end watch brands love more than a certification of quality. Some, like COSC, are industry-wide standards, while others (much like the movement) are strictly an in-house affair. The Patek Philippe Seal is one such certification.  The new Patek Philippe Seal dramatically transcends the original hallmark’s notion of quality and perfection. … ContinuedThe post RECOMMENDED READING: Just what is the Patek Philippe Seal?  appeared first on Time+Tide Watches.

In-Depth: The Microscopic Magic of H4, Harrison’s First Sea Watch

One can understand the opacity of the first published analysis of John Harrison’s first sea watch, colloquially known as H4 and the forerunner of the marine chronometer, in The Principles of Mr Harrison’s Time-keeper. Edited by the British Astronomer Royal Nevil Maskelyne, it was published by the British government in 1767; and hereafter referred to as Principles. Principles was both incomplete of enough information to allow the duplication of the watch, which Harrison (1693-1776) started in 1755 and finished in 1759, and contained somewhat incoherent description that only makes sense a posteriori after examination of the watch. ‘Principles of Mr. Harrison’s Time-keeper’ Amazingly, it was one hundred years later the next review took place. I can echo Harrison M. Frodsham’s comments in his review in Horological Journal of May 1878 when he said, “Former explanations taken from Harrison’s description are necessarily unsatisfactory, as his was very obscure, probably purposely so.”  Although this may be dismissed as 19th Century gossip by some scholars, this may have arisen in part to protect any military advantage, given the importance of H4 to maritime navigation. Considering H4’s historical performance, it is odd that the otherwise comprehensive A Treatise on Modern Horology in Theory and Practice (2ndedition) by Claudius Saunier, published in 1887, barely mentions Harrison and certainly not H4’s technical content. Perhaps it was because it was so quic...

In 1939 when two Portuguese merchants approached IWC about making a wristwatch with the same levels of accuracy usually seen in marine chronometer pocket watches, they had no idea it would be the beginning of a legend and the birth of one of IWC’s most popular collections. With a new slightly revised design, IWC have launched … ContinuedThe post INTRODUCING: The IWC Portugieser Chronograph Classic lives up to its name appeared first on Time+Tide Watches.

Here at Time+Tide we make no bones about being greatly enamoured of Longines’s heritage offerings, so it’s understandable that we made a beeline for the Lindbergh and 1945 models. However, our attention was rapidly drawn to the comparatively pared-back Record, which intrigued us with one simple word on its dial – ‘chronometer’. Now, in case you’re not … ContinuedThe post HANDS-ON: One simple word that makes the Longines Record a big deal appeared first on Time+Tide Watches.
