Funny that you posted this today. I saw a Nautilus Perpetual Calendar yesterday. I didn’t say anything to the guy. Kinda regret it now.

100 metre of water resistance!

Which other watches do you put in that category?

Great collection. Is this your favourite watch?

Awesome watch, I just checked it out on your profile!

The reference number for mine is RA-AP0004S10A. The nickname I’ve seen kicking around online is the Bambino Small Seconds.
