Picked up an old catalogue from 1964 on eBay. They are always fun to study and a great source for collectors to cross-check details. This catalogue has among others the Deep Diver 7897 and the alarm 7742, so a good opportunity to verify some details.
Black dial 7897 Deep Diver:
- Dial: check
- Hands: check
- Bezel: check
- Crown: check
And the 7742 Alarm:
- Case: check
- Hands: check
- Print on dial: check
A nice little treasure.
