Good evening!
Since I "stumbled" over a 3711 I cannot stop thinking about it ... when searching for some size data I came up with:
3711/1G ... 41mm
3800/1 ... 37mm
"Jumbo" ... 42x38mm
Are these right? Do you have any more exact size data of the different Nautilus models?
Thanks so much and greetings from Vienna/Austria,
Harry
