Official or unofficial Nickname (if any exists)
Not aware of any.
The fit and finish is excellent. The dial is simple and easy to read. The hands and hour markers are well polished. It keeps excellent time. Based on the serial number, I believe it was made in March of 1969.
The movement is a 6145-8010, beating at 36,000 bps. Hacks, handwinds, and has a quickset date. This was the lowest grade GS Hi-Beat movement. A variant had day and date, but this one only has date. The hi-beat movement gives the second hand a nice and smooth sweep across the watch.
I don't have any fancy tools to measure accuracy, but I set it according to an atomic clock and one week later it had lost 12 seconds.
Polished stainless steel, although I've put some scratches on it since owning it. Looks similar to the modern GS, with the main difference being that the lugs do not taper in to join the circular case. The case is 36mm excluding the lugs.
This is an acrylic crystal, and it has a couple of scratches. There is a magnifier over the date.
bracelet/strap review (including clasp)
It did not come with the original strap, but I put a Sirtoli Ostrich on it. I am planning to buy a bracelet to wear with it in the summer, as soon as I can decide on one.(Any suggestions?)
