Why it scores as it does
Proportions and movement are computed from specs. Design details and functions are judged from the brand's official images. How we score
Lug-to-lug is neither published nor measured for one of the two watches, so there is not enough data to score.

What reviewers and owners say
Reviewers
From 5 reviews we read or watched.
All five reviewers found the finishing well above what the price suggests. Three praised the 24-click bi-directional bezel (a fourth called it average) and three the feel of the chronograph pushers. They liked the swan-neck Seagull movement seen through the case back, the dome of the sapphire and the leather strap with its custom buckle. One reviewer noted that the bezel and case sit flush with no step between them. Reports on the lume differ: two say it fades fairly quickly, two call it bright and well applied.
The common reservation is size. Reviewers give a lug-to-lug of 50 to 51 mm and a thickness of 13 to 13.8 mm, and three say it suits wrists of roughly 7 inches and up. The crown and pushers are not screw-down, matching the 50 m rating. One reviewer saw 29 jewels printed on the case back where listings say 21, and could not say which is right.
Good
- Finishing praised by all five reviewers for the price
- 24-click bi-directional bezel with a smooth action, per three reviewers
- Hand-wound Seagull ST1901 with a swan-neck finish visible through the case back

- Pushers feel positive, with a clean reset, per three reviewers
Less good
- 51 mm lug to lug and about 13 mm thick, large for wrists under about 7 inches
- Only 50 m water resistance, with a non-screw-down crown and pushers
- Jewel count differs between the case back and the listing
- Lume longevity is reported as fading fairly quickly by two reviewers
