The short answer

The closest alternative to the Citizen Series 8 831 is the Tissot PRX ($850) — common cross-shop and Integrated bracelet sport. If price is the constraint, the Orient 75th Anniversary RA-AC0Q12L30B at $405 (vs $1,095 for the Series 8 831) covers most of the same brief. From the independents, the Christopher Ward The Twelve is the standout microbrand take — common cross-shop and Integrated bracelet sport. Stepping up, the Seiko Prospex Marinemaster Marinemaster 1965 Heritage Diver's Watch ($2,800) is where the same idea goes with a bigger budget.
