What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Serica Ref. 5303 Diving Chronometer

Owners widely praise the Serica Ref. 5303 Diving Chronometer for its excellent wearability, definitive style, and smooth, confident bezel action. The dual scale on the bezel is noted as surprisingly useful, and the crown action, winding, and hacking are reported to work perfectly. One owner describes the Serica 5303-3 as gorgeous and unique, though another notes the crown can appear comically large. On balance, owners rate the Serica Ref. 5303 Diving Chronometer highly for its blend of unique design and robust functionality.

RZE Resolute Type A

The RZE Resolute Type A is praised for its build quality, finishing, and highly legible dial with luminous elements, all at a $499 price point. Its sandblasted titanium case features an UltraHex coating, and it measures 39.5mm by 11.5mm with 100 meters of water resistance. A reviewer notes the Miyota 82S0 movement's crown operation feels grainy. On balance, reviewers highlight the RZE Resolute Type A as a well-built and legible pilot's watch offering good value.
