Moonphase complication in a ss 'tool watch'

[Zsprings]

I have just looked in the brochure at the Cellini Moonphase a great dresswatch and being 50m watertight, it would be ideal for a YachtsMan (but ss rather than the rose gold). Because the height of tides are hugely affected by the moon. Now, we have the YachtMaster II Regatta, but this watch IMO is more aimed towards a skipper, who sails in Regattas or is happy to watch from the shore.

If this 'moonphase' complication could be included in a stainless steel tool watch, with screw down crown, protective lugs and oyster bracelet, this could have the Rolex name 'YachtsMan' or 'Sea Dweller' and become such a useful watch for those of us who sail around the coasts. A true tool watch for yachties !
