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.

Venezianico Nereide Lapislazzuli

Owners widely praise the Venezianico Nereide for its exceptional dial work, particularly the mother-of-pearl blue and lapis lazuli variants, and its well-executed case finishing with consistent brushing and polished edges. The 39mm version is noted for its thin 10mm profile and comfortable wearability, while the bracelet is generally considered good quality. Some owners feel the NH45a movement is a drawback, preferring a thinner and more accurate caliber. One owner specifically noted weak lume on the seconds hand and bezel triangle, along with some play in the crown's hand-setting on the 39mm model. On balance, owners rate the Venezianico Nereide highly for its stunning dial options and refined finishing at its price point.
