The Seiko 5 GMT 4R34-00A0

Seiko released a much-awaited GMT model for their Seiko 5 line. There are three variants - the SSK001 (black and grey bezel, black dial), SSK002 (black and blue bezel, blue dial - "Batman"), and SSK003 (black and grey bezel with orange numerals, orange dial). The models appear to be homages to the very expensive Rolex models that have very similar bezels and dial designs. I have an SSK001, which I thought was the least noticeable among the three.

The watch has 4 hands - hour, minute, second and GMT. It has a date complication.

The watch came with a jubilee stainless steel bracelet.

The watch is not a limited edition and has what looks like a regular serial number. The number though is unusual as it does not seem to be indicate year and month of manufacture. If we follow the conventional interpretation, then this watch would have been made in Feb 2015.

The watch is powered by a Cal. 4R34 GMT movement that runs at 21,600 A/hr with a potential power reserve of ~41 hours. The watch also has hand winding and hacking features. Seiko has made this GMT movement available to other makers, which now makes it possible for others to come up with their own GMT models. Even modders now have a GMT movement to for their homage watches. 

The watch is easily a beater considering the features. It would have been even better if this were a diver and the crown can be screwed down to keep it water tight. Although the watch is rated to have 10bar (100m) water resistance, Seiko could have made this a 20bar (200m) diver.
