Having looked for the right SM300 for ages and then given up the ghost, I was really smitten by the Seamster 60 (ref 166.062) that was listed on TZ-UK’s SC recently. With box and punched papers from 1969ish, it proved to be irresistible and it’s now on my wrist with a nice Tropic strap and the mint bracelet still in the box.

It’s a very wearable size at 37mm, and that’s without a relatively large crown (in fact, this reference has been dubbed the “Big Crown” and you can see why from the photos). It has a deep blue dial and a similarly coloured bakelite bezel – both in fantastic condition – and houses a 24 jewel calibre 565 automatic movement; it doesn’t hack, but the date is quick-set and operated by pulling out and releasing the crown to advance by one day at a time. Water resistance was originally 60m but this one won’t be going swimming any time soon.

I think I’m right in saying that they were only produced from the late 60’s to the very early 70’s so they’re few and far between compared to most other Seamaster models. That aside – what a gorgeous watch!
