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...

The Grand Seiko Spring Drive Chronograph

One of my favourite watch making house is the often overlooked Seiko. They have a long history and tradition of making fine timepieces as well as of innovation.

The ABCs of Time – How Are Mechanical Watches Wound? A Comprehensive Guide to Automatic and Manual Movements

There are basically two types of watch movements – mechanical and quartz. The latter is powered by a battery or a combination of solar and rechargeable cells, while the former is powered by one or sometimes multiple mainsprings with no electrical input. There are also grey areas like Grand Seiko’s Spring Drive or Accutron’s Electrostatic […]

Tissot Introduces the PRC 100 Collection with a New Solar Powered Movement

There are a number of watchmaking technologies that are tough to appreciate until you’ve actually spent considerable time with a watch. Grand Seiko’s Spring Drive comes to mind, especially if you’re inclined to constantly check your watch’s accuracy. The consistency over time of a Spring Drive movement is kind of mindblowing if you’re used to “normal” mechanical watches. Similarly, high accuracy quartz, from any brand, is tough to wrap your arms around until you’ve gone months without needing a reset because your watch is keeping time to within a second or two. And ultra-thin watches deserve a mention here as well. A watch that you literally forget you’re wearing because it’s so thin can be a special thing when properly executed.  But in terms of actually making your day to day life easier, there are few technologies that match the practicality of solar powered timekeeping. There are a bunch of brands that offer watches with solar movements, and for some it’s really become their stock-in-trade. Today, Tissot expands their solar offerings with the new PRC 100 Solar collection, bringing an aging collection up to date with some modern tech that should have broad appeal to both the mass market and the most sensible, practical, enthusiasts among us.  The PRC 100 was originally introduced in the mid 2000s and is easily identified by its dodecagonal bezel. PRC is an acronym that stands for “Precise, Robust, and Classic,” which seems like the right canv...

REVIEW: Getting Out & About With The Bremont Martin-Baker II

Spring is here and a great time to get out and about, so I took the Bremont Martin-Baker II on a couple of outdoor adventures to see how this robust watch holds up in our latest Hands On Review! What We Love Comfortable on the wristBright, easy to read dialOrange colour pops & is fun What We Don’t Crown is hard to pull out and setWears on the larger sideStrap can be a little finicky to put on Overall Rating: 8.25/10 Value for money: 8/10Wearability: 9/10Design: 8/10Build quality: 8/10 For those that aren’t aware off the Martin-Baker story, here’s a quick re-cap. Martin-Baker is a British aviation company responsible for supplying 70% of the world’s Air Forces with fighter ejection seat technology. They first approached Bremont to create the definitive aviation watch in 2007. More than simply putting a logo on an existing model, the watch had to withstand the same rigorous testing programme as the ejection seats themselves. Two years later, the Bremont Martin-Baker I (MBI) was born and limited solely for pilots who have ejected from an aircraft using a Martin-Baker seat – something that is not all that fun and puts a tremendous amount of stress on the body and the watch! The MBI with red case ring – only for pilots who’ve survived a live ejection The MBII and MBIII were then produced for the general public, designed to the same strict standards of the MBI, but available in a range of colours and variants, with people able to choose their own colour for the mid...
