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.

Glycine Combat 6 Classic

Owners widely praise the Glycine Combat 6 Classic for its refined engineering, comfortable 36mm wearability, and exceptionally legible dial with well-executed lume on markers. One owner notes the salmon dial model features a decorated Glycine Cal. 224 movement, an ETA 2824-2. A reviewer points out that while dial markers have good lume, the hands have minimal lume, and the serial number etched between the lugs is visible.
