With the Sealion M55 waterproof case this DX model has extras that the standard watches never had. Model reference 6106-8480.
HOW DO WE DATE THIS WATCH?
From the serial number on the case back we can accurately date this watch to being made in May 1970.
CONDITION
The DX range was a little above the standard Seiko 5 models. As well as things like water proof cases (when new – never get vintage watches wet) and quick set day and date, the DX range also got extra jewel bearings in the movement and the ability to hack the watch. Seiko also spent a little more on tin details, such as the hour markers. You can quick set the day wheel between English and Roman numerals, with Sunday being indicated by a red rectangle. The 25 jewel calibre 6106C movement was never designed to be hand wound, hence the crown is flush to the case. The matte brown dial is a good colour and the condition is great. The leather strap is new, and could be swapped for a different colour if preferred.
This watch will be supplied with our branded presentation box and our Certificate of Authenticity.
