yes it is

Thanks Dracha, some good info on this model anywhere like rarity, etc.?

pffff where to start

Reference 2005
build in the early to mid 60'ies
later followed by a model with separate small seconds hand on the 9 position
heavily modified 7731 movement
quite rare but are offered regularly , are offered less often than the (for example) all black 806 w/ venus 178 and as they were dive watches I think its really hard to find a mint example

I think thats the cold hard facts ?
