Personally, I’d not try and waterproof a Daytona rep. If you want to swim with a rep watch then start with a divers rep, such as a Submariner etc. There are people on the forum that can waterproof them too. Have a look in the modders section.

Both should be fine. Some reps are let down by the bracelet. I own a Pelagos rep and the bracelet (including the clasp) is great. My Sub is a TC rather than a Noob, but the Noob should be fine also.
Post some pics if you buy one.
Last year Micky built me a modded Seamaster Chrono. I had several of these both rep and gen so wanted something unique.
I had a rep that needed a service and a new crown and tube (original was stripped). It started off as a 2225.80 - a post 2008 blue Seamaster chronograph. I asked for Micky to spice it up a bit. He serviced the movement, fitted a new crown and tube then went to town modifying it. A Prof Steve 2xAR crystal and a black date wheel were installed. The hands were coloured as per the new Omega Seamaster Chronographs and an orange P.O. bezel insert installed - because I wanted something different and it was to hand. The result was like this.
However today I found an insert lying around......
Just for shits and giggles. Not sure yet.
