The problem of internet pics... That?s not a Sea Hawk...

 

Hi Kevin,

that?s a ref. 49530 Classique Elegance Big Date/Moonphase:

The Sea Hawk would be either reference
- 49900 (regular, 42mm)
- 49910 (John Harrison)
- 49920 (regular, 40mm)

I?ve yet to see a Sea Hawk with a crystal back and frankly, i don?t expect to see one soon.
The crystal back causes a lot of problems in terms of depth rating/water protection (that?s why Rolex don?t use them), so it?s somewhat difficult to include it in a diver?s watch.

Regards,

Peter
