The new Speake-Marin in-house movement SM2

Over view
The over all design of the movement is based on the philosophy of precision and longevity. The movement is large and unique in style, it retains the S-M signature winding rotor and returns to ‘the foundation watch’ style of circular grained untreated German silver bridges.

One of the approaches in designing the movement was to make a watchmakers watch, meaning that the priority was to make it in such a way that would facilitate the
assembly and adjustment for the watchmaker to be able to affect his skill with ease and precision. Examples of this are shown by the double micro regulation for the beat error and timing of the balance, as well as the milling around the balance gaining maximum access to view the balance for adjustment. In addition windows are milled into the sides of the movement to allow maximum visibility. The escape wheel bridge can be removed independently of the main train bridge to allow the escapement to be assembled separately of the rest of the watch.

The SM2 will replace our existing FW2012 automatic movement during 2009.

The MARIN-1 is the first Speake-Marin model to integrate the SM2 caliber.

About Peter Speake-Marin

Born in 1968 in the county of Essex in England. First studying horology London’s Hackney Technical College and then later at the prestigious Swiss watch making school WOSTEP in Neuchatel. This was followed by seven years in the heart of London’s Piccadilly, where he worked as a specialist in the restoration of highly collectible antique watches.

This period gave him the opportunity to be in intimate contact handling and restoring literally hundreds of horological treasures from the greatest watchmakers and houses in history. The inspiration and knowledge gleaned from those treasures fired his desire to work and further his knowledge of watchmaking to an even higher level.

Returning to Switzerland in 1996 to work on modern watches he specialized in complications both building them and in their development.

In 2000, after 15 years of study he embarked on his personal dream; an independent workshop in which he could design and build his own watches.

The Watch Workshop is the name of the company founded by Peter Speake-Marin to realize his ideas in watchmaking..


As a graphic designer, I'm fascinated by the crossroads between technology and aesthetics. Horology is one of these crafts, where art and engineering come together to produce mechanical wonders that grace the eye. WatchPaper was born from the desire to create an online tool where I can share my passion for watches.
