The Speedmaster Workshop

For watches you do not entrust to just anyone. Servicing, restoration and thoughtful preservation – with a special focus on the Speedmaster.

01 / Speedmaster Edition
The edition

A dedicated stage for an exceptional chronograph.

The Speedmaster has been part of Robin Israel's workshop life for many years. Here it receives the attention its mechanism and its history deserve.

Whether a classic Moonwatch, an early calibre 321 watch or an unusual Mark-series model, every mechanical Speedmaster takes priority in our workshop. Once the work is approved, we start directly or place it in our dedicated Speedmaster queue. This means it is attended to considerably sooner than other watches. We determine the scope of work for the individual watch.

Our standards

Mechanism at its best. Character preserved.

A good service must deliver reliable operation. A good restoration also recognises the elements of a watch that cannot be replaced.

01 / Precision

Thorough attention to the movement

From preliminary cleaning by hand, through carefully tailored cleaning and lubrication, to regulation and final inspection – every step has its purpose.

02 / Original material

Restraint on the exterior

The dial, hands, luminous material, bezel and case edges are treated as part of the watch's history. We discuss any intervention beforehand.

03 / Transparency

A documented service

We explain our findings and the options clearly. Every watch receives an online service passport bearing its serial number. With Exclusive Service, this is supplemented by a certificate that can be downloaded as a PDF and shared by link.

The family

More than the Moonwatch.

From early calibre 321 references to the distinctive shapes of the seventies and eighties – the Speedmaster has many faces.
