VIDEO: Is the Tissot Seastar 1000 Powermatic 80 the best-value diver of 2018? 

This is such a great watch. Honestly. I can’t think of many (if any) Swiss-made watches that offer such a punchy package for this sort of price. Not only do you get the impressive Powermatic 80 movement (more than three days of power reserve rocks) in a good-looking, well-made 300m diver, you get nice little … ContinuedThe post VIDEO: Is the Tissot Seastar 1000 Powermatic 80 the best-value diver of 2018?  appeared first on Time+Tide Watches.

MICRO MONDAYS: Marin Instruments create a skin diver for the 21st century

For those who were into scuba diving in the 1960s/70s and did not care for the professional-grade dive watches from Rolex and Blancpain, skin divers offered a more wearable and equally cool horological experience. Skin divers got their name from the fact that they were meant to be worn directly on the skin and not … ContinuedThe post MICRO MONDAYS: Marin Instruments create a skin diver for the 21st century appeared first on Time+Tide Watches.

What is a Chronometer Watch? A Guide to Ultra-Precise Watches

When a watch touts on its dial that it is a "Chronometer" or an "Officially Certified Chronometer" or even a "Superlative Chronometer," what exactly does that mean? How does a chronometer watch differ from a watch that does not make that claim? For that matter, a newbie to the timepiece game might ask, what is the difference between a watch with "chronometer" on the dial and a watch with "chronograph" on the dial? In this comprehensive guide, we attempt to answer all of your burning questions about chronometer watches and what sets them apart. [toc-section heading="The Chronometer Throughout History"] Our original, classical definition of a chronometer can be traced back to the golden age of seafaring exploration in the 18th Century, when ships required the use of a highly accurate onboard clock that enabled their navigators to determine longitude in order to avoid the perils of running aground or veering hopelessly off course. The man credited with developing the first of these “marine chronometers” was legendary British watchmaker John Harrison; his invention facilitated the celestial navigation used at the time by navigators at sea to determine their ship’s position in coordination with a sextant. Marine chronometers, which were essentially highly accurate clocks mounted on gimbals inside wooden boxes, were among the first portable timepieces and were instrumental in the global seagoing trade that helped build our modern, interconnected world.

Citizen Unveils their Latest Washi Paper Dials from “The Citizen” Collection

As I’ve gotten more and more involved in the watch world over the years, something that’s become a great interest to me is accessible craft in watchmaking. We all know that you can spend five figures (or more) on a watch and get a movement with meticulously hand finished and polished bevels, for instance, but what I’m really drawn to is the brands that are able to do impressive things the old fashioned way at more accessible price points. Think of anOrdain’s enamel dials, for instance, or the handmade silver cases from James Lamb. We frequently look to smaller operations for this kind of work, but large brands are capable of surprising us with unusual craft techniques as well, and we were reminded of that a few weeks with the introduction of a pair of new watches by Citizen using their impressive Washi paper dials.  These watches fall into The Citizen collection from Citizen, one of my favorite names for a collection, even as it drives my editor brain kind of insane. Yes, the watches are called “The Citizen” in the same way the iconic diver made by Rolex is the “Submariner.” I’ll be honest, I don’t know the origin of the use of the definite article in the collection’s name, or anything about the decision to name these watches after the brand itself. Frankly, I don’t want to know, because I like the story I’ve created in my head of Citizen creating a collection that they feel perfectly defines their brand to such a degree that you could call it Th...

In-Depth: Philippe Dufour Grande Sonnerie Pocket Watch No. 1

A quartet representing the entirety of Philippe Dufour’s repertoire went under the hammer last year, with the Grande Sonnerie wristwatch no. 1 setting the record for any Dufour sold publicly when it achieved the equivalent of US$5.2 million including fees. Sold at the same auction, but for substantially less, was the Grande Sonnerie pocket watch no. 1. Despite the relative values, the pocket watch is arguably a more significant timepiece within Mr Dufour’s work. Why? Initial thoughts In today’s wristwatch-centric era, the fact that it is a pocket watch counts against it. That was also the verdict of the market – the pocket watch sold for half as much as the wristwatch in November 2021. But the Grande Sonnerie pocket watch is the ultimate distillation of Philippe Dufour’s philosophy, the ideal synthesis of the inspiration and impetus behind his creations. He has long stated, both publicly and to me in past conversations, that his watches are a reverential homage to the haute horlogerie produced in the Vallée de Joux during its heyday before the Quartz Crisis, the period between the late 19th to the mid 20th centuries. Timepieces of that era, especially those with ebauches made by the valley’s best specialists like Louis-Elisee Piguet and Ami LeCoutre, are the best watches ever made in Switzerland in his view. And the Grande Sonnerie pocket watch can pass for a timepiece from the late 19th century, perhaps even one made by Mr Dufour’s favourite historical w...

Auction Watch: Philippe Dufour Simplicity Sells for Record US$662,000

Sotheby’s fall watch auction in Hong Kong included a diverse selection of independent watchmaking, including two examples of the Philippe Dufour Simplicity, both with silver guilloche dials. The first to go on the block was a 37 mm specimen in white gold with a movement number of 68. It sold to a client represented by Joey Luk of Sotheby’s watch department for HK$3.528m including fees, which is a little over US$455,000. That was substantially above the US$250,000-300,000 range that the Simplicity had generally sold for, setting a new record for the model. The next lot was a 34 mm Simplicity in platinum, numbered “100”. And then the record was broken. After a few minutes of back and forth between an online bidder, as well as phone bidders represented by Ms Luk and John Chan, also of Sotheby’s watch department, Mr Chan’s bidder triumphed with a bid of HK$4.1m. Inclusive of fees, the total was HK$5.136m, or about US$662,000, well over double the most recent high for the Simplicity. Part of the reason behind the price is rarity, not only absolute but also relative to other Simplicities. Platinum is unquestionably the rarest metal version for the watch, and 34 mm examples is are regarded to be fewer than 37 mm. The record price for both watches bode well for the Simplicity 20th Anniversary “00/20” – fresh from maker and offered by Mr Dufour himself – that will be sold at Phillips’ November auction in Geneva.  

Behind the DIN 8330 Standard for Pilot’s Watches

Standards and certifications in watchmaking were primarily developed for chronometry, as well as to reassure the buyer that their watch had been thoroughly tested to a certain level of accuracy. The standards we see most often in the technical specifications are COSC, METAS, and other company or regional chronometry certifications. In modern watchmaking, other key standards like the ISO 6425 dive watch standard, which was developed in the 1990s and followed by watch companies, also come into play. These standards were largely based on various military set standards for watches; however, since each military set their own requirements, there was not one universally followed standard. The International Organization for Standardization (ISO) published specific requirements and testing procedures for a watch to be officially designated a “Diver’s watch”. While there is no ISO standard for pilot’s watches, there are specific requirements set by militaries around the world. One of the most well-known standards is from the WWII German pilot’s watch known as the “Beobachtungsuhren” or “B-Uhren.” B-Uhren pilot’s watch standards are well documented and are still followed by many watch companies to this day. In March 2012, Sinn lead an initiative in collaboration with the Faculty of Aerospace Technology at the Aachen University of Applied Sciences to create TESTAF – Technical Standard for Pilot Watches. TESTAF was developed so that a pilot’s watch meets all mod...
