The Watch & Movement
Incredibly rare IWC Schaffhausen vintage watch, dating back to the 1950's.

The case for this watch, as you will see from the initials on the case, is D. Shackmen and Sons, who made cases for leading houses of the day, including Rolex and Omega. Because of gold import duties, big houses imported their movements, dials, and hands into the UK to be housed by specialist English case makers such as Shackmen. They also made bracelets and other products for most of the major Swiss brands for use with their watches and other products, which were sold both in the UK and Europe. They were based in Chesham, Buckinghamshire, England.

Shackmen even made one-off pieces housing IWC movements for clients, much like this example. The other great English casemaker, Dennison, closed in 1967, after which Shackmen became the preferred casemaker, so this is an important example as it houses an iconic calibre IWC 89 as specified for both military use and other high-end watch makers like JLC and other famous brands that I have referred to.

This IWC houses the iconic calibre 89 movement and was designed by Albert Pellaton, a fine designer of movements who cut his teeth at Vacheron Constantin before moving to Schaffhausen as their technical director in 1944. The 89 was his first work for IWC and was based on the calibre 83. The 89 was first used in the Ministry of Defence’s MKX1 pilot watch before finding its way into civilian watches. The 89 is considered by many of us collectors and horologists to be the pinnacle of both movement design and durability.

Fully working order, with a stunning patina dial.

Case size is 34mm, with a lug to lug width of 41.8mm and thickness of 9.5mm. Lug width is 17mm.

What’s Included
This IWC comes on a generic strap and aftermarket clasp (not original IWC). No box or papers included with this piece.

We tend to not polish our watches before listing for sale, this is because we have always preferred to keep as much metal on the watch as possible and preserve the shape. We are able to offer a polish as a free service, just let us know if you wish for this to be done and we can have our watchmaker complete. This will add 4-5 working days to dispatch.
