In-Depth - Deciphering the Revolutionary Rolex Dynapulse Escapement and the Calibre 7135

Rolex has changed… Not marginally, but significantly. We knew the brand was capable of being rather unpredictable and capable of bold creative moves, such as bubble-decorated dials and watches with a guilloché pattern. The days when Rolex simply revamped a collection every 10 years by implementing incremental upgrades and releasing new dial colours every two […]

Insight: What’s Next for the Girard-Perregaux Constant Escapement?

In an era of modern and accessible digital technology, the utilitarian role of mechanical timekeepers has inevitably dwindled. Yet, it is still pursued as a luxury of an artform – either of the highest finishing by hand that can’t be performed by machines, or the research and development in making a mechanical timepiece – in particular wristwatches – as accurate as possible.  One of these horological pursuits, to preserve the accuracy of mechanical wristwatches, is the supply of a constant force to the escapement. To isolate the varying torque as a mainspring gradually unwinds, some haute horlogerie watches today incorporate either a fusée-and-chain or a remontoir, which supplies a steady torque to the escapement for stable timekeeping.  However, there is one particularly novel take on constant force released by Girard-Perregaux, in the form of a proprietary escapement. First unveiled as a prototype in SIHH 2008, the Girard-Perregaux Constant Escapement has a patented, double escape wheel system that is designed from the ground up to inherently have a built-in constant force system, thus eliminating the need of a remontoir or a fusée-and-chain.   Despite being first created 15 years ago, Girard-Perregaux (GP) is still further developing the escapement today, with a new set of patented improvements publicly available – strongly hinting at a revamped model in the near future. These patents make it worth a deep dive into the original Constant Escapement (CE) fr...

Grand Seiko Spring Drive Guide

Japan’s Grand Seiko has become, in a relatively short span of time, one of the world’s most prestigious and collectible high-luxury watchmakers, competing for connoisseur attention and dollars with well-established maisons from Switzerland and Germany. And while its success is definitely a 21st century phenomenon, Grand Seiko is not really a “new brand” in the strictest sense. The first Grand Seiko watch (below) debuted all the way back in 1960, part of the much larger product portfolio of Japanese watchmaking giant Seiko, which was founded in 1881 and achieved its worldwide fame by embracing the mass market with timepieces at accessible prices with wide distribution. The Grand Seiko, by contrast, was positioned as the megabrand’s exclusive “King of Watches,” with standards of accuracy, beauty, durability, and legibility that could meet or surpass its Swiss competitors. Until 2010, it was also Japan’s best-kept horological secret, not exported to markets outside the country. Seven years after its international expansion, having cultivated a loyal and avid audience worldwide, an entirely new and distinct customer base apart from mainline Seiko’s, Grand Seiko firmly established itself as an independent brand - albeit one still intrinsically tied to its parent company through shared history and technology. Among those technologies is an innovative type of watch movement that was perfected right before the turn of the 21st Century and remains the exclusiv...
