Wessex Automatic Watches

The handmade engraved silver dial of a Wessex timepiece is obviously the component that sets us apart from other watch brands, but a high-quality watch demands a high-quality movement.

To do justice to the time and effort that we put into producing our transcendent and peerless dials, every single one of our watches has a top-quality Swiss movement to drive it.

In the case of our automatic watch collection, that movement is the STP1-11 calibre from Swiss Technology Production (STP).

A relatively new company, STP were formed in 2008 and by 2012 had become a subsidiary of the American watch giant, Fossil Group.

With massive investment from the new owners, STP now boasts the most technically advanced mechanical movement production facility in Switzerland, no mean feat for a company only 11 years old!

We chose the STP over other comparable movements not only because of the very high-quality standard of the components (all the components are sourced from and manufactured in Switzerland), the exceptional build quality of the movement and the outstanding finish of the calibre, but also because unlike many of the other manufacturers, we can deal directly with STP to obtain our movements in relatively small quantities, so the movements we buy are made and customized specifically for us, in other words, 'we know where they've been'!

It is no wonder that the STP range of movements are used by a growing number of, not only Swiss watchmakers, but many brands worldwide.
