Now in the correct section

As per the title, but not along those lines of hot sports models you wish were at retail & available.

But more along the lines of brands & models that are currently available, but with some minor tweak that you wish were in production.

A few of the top of my head:

Panarai to make either a base 42mm or 40mm version of the iconic 372 (47mm 1950s case they made & not the 390 which people often think is a smaller version).

Omega Seamaster, current edition but sans HE valve & no date. I could live with the sword sea through hands.

Omega Speedmaster Pro - just give it 100m and make people feel more comfortable about swimming with it.
