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.
Proportions— / 30
- Case diameter8 / 121 mm apart
- Lug-to-lug0 / 8Not published, left out
- Thickness4 / 61 mm apart
- Lug width4 / 4Same size
Design signatures— / 40
- Large snowflake hands in luminescent composite4.5 / 9Hour hand is a broad lume block with a pointed, angled tip and the minute hand is a thick lume baton with a pointed tip; the weight and lume plots echo the original's large hands, but the shapes are not snowflake hands.
- Enlarged tachymeter chapter ring on a sloped rehaut, scaled for cycling speeds0 / 8No enlarged tachymeter scale is visible in the official images; the dial has a plain minute track and the scale on the bezel is a dive-style 60-minute one.
- Black carbon composite case with matt finish0 / 8The case is brushed titanium in the official images, not a black carbon composite.
- Central seconds and 45-minute counter chronograph layout2.5 / 5Three sub-dials (running seconds at 9, 24-hour at 3, chronograph minutes at 6) with a central red chronograph hand, a different layout from the original's central seconds and 45-minute counter.
- Square applied hour markers shifted inward to clear the chapter ring2.5 / 5Large square applied markers with lume sit inside a minute track on the dial; the images do not show them shifted inward to clear a chapter ring, and there is no raised chapter ring.
- Two direct-action pushers flanking the crown3 / 3Two screw-style pushers flank the crown on the right of the case in the official images.
- Fabric strap through fixed lugs2 / 2Woven nylon strap passed through fixed lugs with strap slots, closed with a titanium buckle.

What reviewers and owners say
Reviewers
From 3 reviews we read or watched.
Three reviewers found the titanium case light and comfortable, with a nylon hook-and-loop strap and a titanium buckle. All three praised the lume, which also covers the sub-dial hands, and all three noted the date window is very small, between 4 and 5 o'clock. Two confirmed a sapphire crystal with AR coating and screw-down crown and pushers. Two give about 50 mm lug to lug (49.9 and 50), in line with the 42 mm case and 22 mm lugs.
The bezel is the main point of disagreement: one reviewer found it weak with complete back play and counted 60 clicks, another found the action fine and counted 48, and a third called it a 40-click bezel (possibly misheard in the captions). The reviewers who say they bought it paid roughly $125 to $179.
Good
- Light titanium case
- Solar movement with no battery to replace
- Large lume plots on the markers, hands and sub-dials
- Sapphire crystal with AR coating
- Three dial and strap combinations
Less good
- One reviewer found the bezel action weak, with full back play
- Reviewers give different bezel click counts (60 in one review, 48 in another)
- Very small date window (one reviewer)
