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.

Grand Seiko SBGD202

The Grand Seiko SBGD202 is widely lauded for its mesmerizing "Starlight" or "stardust" dial, achieved through a new plating and painting technique, and its exceptional craftsmanship, which reviewers compare favorably to high-end Swiss and German brands. The manual-wind Caliber 9R01 Spring Drive movement offers an 8-day power reserve and impressive accuracy up to 0.5 seconds per day, with an independent hour hand setting. However, some owners find the movement finishing on the display back to be plain. The SBGD202 is priced at 52,800 Euros. On balance, the consensus is that the Grand Seiko SBGD202 is a highly beautiful three-hand watch, with its dial and movement accuracy being the primary reasons for its acclaim.
