From the unfortunately named Blackie series, this Custom V2 has a treat aluminium case and an automatic movement.  Model reference 4-720083TA

HOW DO WE DATE THIS WATCH?

From the serial number on the case back we can accurately date this watch to being made in February 1970.  The movement was first launched in 1969.

CONDITION

This series of watches were named Blackie because of the cases.  The black watches are actually an aluminium alloy with a hard anode oxidized layer called hardermite. As such it is not a coating, but a surface treatment. The light alloy was marketed as having 1/3 the weight of stainless steel, and the hardermite layer as having twice the surface hardness of stainless steel.  Even 50+ years later the surface is still very much black, with just a few places showing the base metal.  PVD would have worn off the case back by now for sure, so the treatment was effective, and it does give a very stealthy look.  Inside you will find a 23j automatic movement, calibre 7290, which has day and date and can be hand wound (unlike many Seiko watches of this period).  On this Custom V2 watch the date can be quick set, but the English calendar wheel for the date can not be – it changes at midnight instead.  The later rubber strap is has been cleaned, and could be swapped for a leather strap if preferred.

This watch will be supplied with our branded presentation box and our Certificate of Authenticity.
