Nick & Giles English
The Bremont Watch Company
It has taken more than three years of research and development to bring the first series of Bremont watches from the drawing board to reality. The high standard of finish and attention to detail seen in everything from the hand-cut and engraved winding rotor in the sapphire crystal case back to the meticulous machining of the three-part 'Trip-Tick' cases take considerable time and skill to apply. As a result, no more than 1,000 examples of each model will be produced annually
An individual record of each watch will be kept at the Biel-Bienne workshops for security and servicing purposes, and all Bremont watches are supplied in beautifully crafted wooden boxes, along with a spare strap, and the accompanying Chronometer certificate.
