The back is a bit unusual, as this is a special edition made for the jeweler Wempe in Berlin, one of the biggest German jeweler chains. This one is the 9th out of a 125 watches made, celebrating their 125th anniversary. The movement has not the usual plating and decoration, but has a sandblasted brass finish, with the Berlin bear engraved and blackened. Very nice indeed.
The movement looks exactly like the Nomos in-house alpha, as it has a single bridge for barrel and gear train, and the typical click, but it’s stamped as “ETA 7001”. The 7001 has two separate bridges, and a different click construction, so I wonder what happened there 😉
Considering that Wempe had their 125th anniversary in May 2003, and that the Nomos alpha calibre was released in April 2005, my guess here is that this is a pre-release alpha. As the alpha is based on the Peseux/ETA 7001, it looks like Nomos didn’t stamp these movements as alphas, but left the original stamping on the plate. Interesting!
One of the best looking manual wrist watches (in my humble opinion).
