Seiko Seiko 5 Sports Dual-Crown DivervsSan Martin Compressor Diver

Owners widely report that the Seiko 5 Sports Dual-Crown Diver SRPB29 lacks a screw-down crown, which one owner finds disqualifying for sports or water use. One owner notes the crown position is awkward and the watch feels too tall and bulky, with material quality around the date window not standing out for its price point. Another owner prefers a 38mm size for a diver, finding the 42mm SRPD55 too large. On balance, owners express reservations about the Seiko 5 Sports Dual-Crown Diver SRPB29's practicality for water activities and its perceived value compared to other brands.

Owners praise the San Martin Compressor Diver as a favorite with a retro diver character, and one notes the big numerals grow on them, though they regret the original black dial didn't sell better. One owner reports timekeeping of only about 20 seconds gained every 12 days under daily wear with the NH35 movement, which is a strong result for an automatic. Weaker points include lume that one owner finds much weaker than expected for the brand, and a lollipop seconds hand that another considers oversized against the dial. Overall, owners rate the Compressor Diver well for its retro homage character and accuracy, with lume the most notable drawback.
