    The finer detail you’ll want to know...


    It is not completely unexpected to find that the world sets its time by Greenwich and not by Geneva. Whilst Geneva and Switzerland may be producing the vast majority of luxury wristwatches today, this certainly wasn’t always the case. In 1800 half of the world's watches, around 200,000 pieces a year, were produced on British shores by British watchmakers, which is an incredible statistic. Another wonderful statistic is that probably over 60-70% of the innovation in a modern day mechanical watch has come from Britain, including every major escapement design. Bremont's mission has always been to play a part in bringing back watchmaking to British shores.
