With a seemingly infinite horizon and miles of clear blue water, no one would argue that time spent on the flats wasn’t time well spent. It’s for those days that the Flats Chronograph was designed. While most chronograph watches use the stopwatch function to determine speed, we've turned the tachymeter scale on its head and adapted the stopwatch function to judge distance. For someone on the flats or in the open expanses of the backcountry, the Flats can be used to calculate the distance of a coming storm. Built for the most extreme marine conditions, the Flats is a certified dive watch and has a 200 meter/20 ATM water rating.

From our customers


100% impressed over and over again by Jeff & Co at Revival. They’re patient and kind no matter the enquiry (currently resto-modding an R100/7 and have LOTS of questions about the Motogadget rewire) and go out of their way to offer creative solutions and out of the box thinking. I will forever return and recommend Revival.

I cannot recommend Revival Cycles enough. Not only do they have a great assortment of gear and accessories but they provide superb customer service. I was having some difficulty making it work... Jeff pointed out what I was missing and also provided schematics to make it work. Thank you guys very kindly, your crew rocks.
