Seiko

Wearing today after recent service and my adjustment of the regulator

 

Bought this Seiko 5 in early 1969 from a small jeweller in Changi village when I was flying into and out of Singapore on C130's.  Ref: 6119B movement and 7100 on the case's back.  Original bracelet, dial and hands.  Was very accurate when new and was thus a popular watch bought among fellow aircrews passing through Singapore because of day/date feature when slipping aircraft at overnight stops in remote locations.

I admit day/date likely now spoils the dial.  In late 1960's, coloured dials offered by Seiko became fashionable among my colleagues.  I had to pay 25% duty on my return to UK because we had customs officers checking at my UK RAF transport base meeting incoming aeroplanes!  I still have the box and papers.
Been wearing this Seiko for three days now and accuracy deviation is less than -1 1/2 seconds per day.  There is no tang on the regulator, which makes fine adjusting a bit demanding.  Average beat error over five positions is 0.44, which is not bad for a 56 years old watch!
The movement has no direct connection between the crown and mainspring.  However, it only takes a couple of shakes to get going and soon winds up on the wrist.
I originally wore this for a few years, alternating with my Omega 1953 ref 2777 and then after my RAF retirement I bought other watches.  This Seiko was then worn only when it substituted for a watch sent for service.
Design-wise I find the steel cushion shape and case's thickness a bit unfashionable now, but as a "tool" watch it was very functional and robust.
I like the round gilt finish of yours and that justifies the fitting of a PP strap.  I have a PP strap on my gold G-P ref 2730.
