Rare .... no: ULTRA RARE: the IWC Ocean 2000 ref. 3500 in black "TiCon"
They probably made 100 to 200 of these blackout Titan Ocean 2000 back in ca. 1985 (this watch is from February 5, 1985). Cheers, HSTE ...
Interestingly..
(If you follow such things..), two ticon 500s for sale recently in the Far East - one terrestrial auction house in HK and the other on YJ.. al
