Here's mine - 166.0XX - exact reference is on a hard drive buried in a box somewhere.

As long as I'm posting, a couple of questions for the experts, if you don't mind...

Is an unsigned crystal of this vintage always indicative of an aftermarket replacement, and does the crown look too small?

166.032 reference
Yes pretty sure all of the crystals from that era are signed in the centre. Doesn't impact value that much tbh though so don't worry about it. If you did ever change it in the future, just make sure you get one with the correct colour tension ring
Crown looks ok to me, likely a service replacement which is fine as the original was likely worn out and a source of moisture ingress

Thanks for the response - confirming as I suspected these answers to my questions.

Fired the old guy up today. Regretting that I trimmed my fingernails yesterday! 😁

Here's a pair:

Rule of thumb - for these models the solid caseback says waterproof for the 18k gold models and has the omega symbol for the non solid gold ones.
