The short answer

The closest alternative to the Sheffield 1A diver ~40mm 3-hand, Arabic numerals (12/3/6/9), no date is the Orient 75th Anniversary RA-AC0Q12L30B ($405) — skin-diver style and Automatic. From the independents, the Sheffield 1A is the standout microbrand take — shared caliber (Seiko NH35A) and Same family (1A). Stepping up, the Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition ($1,350) is where the same idea goes with a bigger budget.
