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 4 reviews we read or watched.
Four hands-on video reviews of this model agree on size and finish. Reviewers describe a 40 mm case, 12 mm thick, that suits a wrist of about 6.2 inches. They also note the brushed case and bracelet, which two called better finished than they expected for the price, an H-link bracelet that is comfortable, and a signed butterfly clasp.
The main criticism is the lume on the hands. Three reviewers describe it as thin, patchy or very poor, and one saw the hands almost lose their glow during a 15-minute test. One reviewer notes that the bracelet has no micro-adjustment, so the fit depends on the clasp. One reviewer measured about +9 seconds per day on a single test. Two reviewers noted that the bracelet links are held by pins rather than screws; one read an NH35A through the display back, and one found a few marks and pitting on the steel of his unit.
Good
- Integrated H-link bracelet with brushed links and a signed butterfly clasp that reviewers found comfortable
- 40 mm wide and 12 mm thick; one reviewer found it sits well on a 6.2-inch wrist
- Brushed case and bracelet
- Screw-down caseback with a display window
Less good
- No micro-adjustment on the bracelet, so the fit depends on the clasp
- The first bracelet link sits slightly proud of the case
- The plain white date window at 3 o'clock was called unnecessary by one reviewer
- Bracelet links are pinned, not screwed, per two reviewers
Known quality issues
Each reported by at least two independent sources.
- Reviewers report thin or patchy lume on the hands, and one saw the hands almost lose their glow in a 15-minute test. A third called it the poorest lume he had seen on a Pagani Design watch.
