Advice pls: U-Boat Nightvision

[Jeuzef]

Any helpful brother or sister out there can advise on the U-Boat Nightvision 53 AS 1R, on details such as where can I buy one in SG. Information which I can find online is sketchy at best about the watch, such as ETS 2824 mechanism, 10 ATM WR etc.

Any brother or sister out there who owns one? T

Thanks for any help rendered.
