What reviewers and owners say
Reviewers
From 5 reviews we read or watched.
Reviewers praised the machining of the shroud and case, the 120-click bezel action, and the dial finishes, with four of the five describing the lume as strong or good (the fifth did not give a verdict). They noted that the very short lug-to-lug of about 44 to 45 mm makes the watch wear compact despite a case width of around 47 mm and a thickness of 14 to 15 mm, and that it weighs about 200 g.
The bracelet drew the most criticism. Two found the links loose, rattly or cheap-feeling and said it let down an otherwise well-made case; one of them also noted push pins and a pressed clasp, and two others called the clasp basic. The bezel pip and the triangle at 12 are not luminous, which reviewers saw as a weakness on a 300 m diver. Timekeeping on the units tested was within a few seconds a day for most, with one unit running slow in some positions.
Good
- Well-machined shroud and case with smooth edges, per reviewers
- Strong lume on hands and indices
- Smooth 120-click bezel action with no play
- Short lug-to-lug makes it wear compact for its width
- 300 m water resistance and sapphire crystal
Less good
- Bracelet reviewed as loose and rattly, with a basic pressed clasp
- The bezel pip and 12 triangle are not luminous
- About 15 mm thick and 203 g
- Case is much wider than the brand's 41 mm bezel figure
Known quality issues
Each reported by at least two independent sources.
- Two reviewers found the steel bracelet loose, rattly and cheap-feeling compared with the case; one also reports push pins and a pressed (stamped) clasp.
