Never taken a cruise - watch options for the trip?

[bobernet]

I’ve been opposed to cruise vacations for a long time, but have agreed to take my wife, kids, and in-laws on one this holiday season. It’s relatively short - 5 days, I think. Two port stops, Cozumel and some private island in the Bahamas (Coco Cay).

I’m planning on taking three watches. One on a strap for day to day. One Rolex for pool/hot tub on the ship. One diver for the island day and actual diving in Cozumel. For those who cruise, does this make sense?

I think I’ve narrowed it down to a gold option or platinum option.

1. 5270J, 118238 ivory pyramid dial
2. 5370P, 228206 blue motif/stick dial

For the diver, I’ll probably take my AP blue/yellow ROO diver, but have considered my Blancpain FF Ocean Commitment 3 (40mm).

If it matters, the cruise line is Royal Caribbean. Thanks!
