Which strap for Planet Ocean deployant clasp

I have a 39.5mm Planet Ocean with 19mm lugs and both Omega bracelet and black rubber / leather strap. I don’t like the rubber strap so much as it does not follow the shape of my wrist due to the sharp angle it holds on the watch. As a result, the watch kind of protrudes and does not sit in contact with my wrist and ends up rotating and sitting at a weird 30 degree angle.

I am looking to sell the strap and keep the deployant clasp. Any suggestion for a strap brand I could buy that would be 19mm watch size, 18mm strap side and compatible with the clasp?

You’ll need to go bespoke as options for 19mm tapering to 18mm are pretty rare. It’s usually 19 taper to 16 or 20 taper to 18.
