Something a little different today on the blog as I predominantly featured mechanical watches in the past. This article is about the service of a British Military Watch, the CWC G10. This watch was issued to a member of the British military in 1980. It is powered by the Quartz movement ESA 536.121. This particular model is the first incarnation of the many G10 versions, and is nicknamed “fatboy” due to its thicker case profile in comparison to subsequent models.
As you can tell from the photo below the watch does certainly look like it has hard a hard life!

Peter sent me this Omega Chronostop Geneve watch for a service and a bit of TLC. The watch is not keeping good time and has a “sticky” pusher.
This quirky vintage chronograph is powered by the Omega Calibre 865, and has an unmistakable design with a crown at 4, and a one pusher operated Chronograph complication.
