Rolex Oyster Royal 6426 Calibre 1215 – Service

Featured on the blog today is this lovely vintage Rolex Oyster Royal 6426 Calibre 1215. This particular watch was produced in 1955 according to its serial number, and it is powered by the excellent and beautifully finished Rolex Calibre 1215: a  manual wind movement, with centre sweep second, Breguet hairspring and shock resistant settings on both balance and escape wheel, a very nice spec for that era.

Seiko SKX NH36 movement upgrade

 

UPDATE: I have now setup a new website dedicated to Seiko mods – for details please visit http://suwamods.co.uk 

 

 

The NH36 movement upgrade can be carried out on the SXK007 or SKX009 (7S26-0020) watches as detailed below. It consists of the replacement of the original 7S26 movement with a “modern” Hattori NH36 (or Seiko Calibre 4R36), which has a hack and wind facility.

CWC G10 Fatboy1980 Military Watch ESA 536.121- Service

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!

Certina DS-2 Automatic Calibre 25.651 – Service

I have been meaning to feature a Certina DS-2 for a while on the blog. Having a penchant for vintage divers watches, the iconic “turtle back” originating from the late 1960s is certainly worthy of a feature, with its substantial look and novel design. It is powered by an in-house automatic Certina Calibre 25.651. One of the particularities of the DS-2 range is the floating movement design, where a rubber ring is sandwiched between the case and the movement, to absorb energy in case of a shock.
