Great watches, Graham, thank you for posting the photos.
A couple of years ago, I also bought a "Hi-beat" GS, unfortunately, it was a 28800, 56 calibre (very much like yours, different face texture)... and I really wanted the 36000, what to do? ? Buy one. Oh dear... I now longer have the 56, but I have the Hi-beat.
Lovely understated watch.
