What reviewers and owners say
Reviewers
From 4 reviews we read or watched.
Reviewers liked the 38 mm size, the finishing and the bracelet. The satin-brushed case with polished bevels, the screw-down crown, the domed sapphire crystal and the screw-pin bracelet with a milled clasp and four micro adjustments were praised, and the BGW-9 lume was described as well applied. The watch wears compact: reviewers measured lug-to-lug at 46.5 to 46.8 mm.
Reviewers measured the case at about 12 mm thick against the brand's 10.8 mm. Every reviewer who named the movement found an NH35 with a ghost date position, which two of them disliked on a dateless watch, while the current listing offers a PT5000 or ST2130. One unit had a speck of dust on the dial near 9:30, which one source reports. Reviewers describe the design as following the Tudor Ranger, with a basic movement in place of the original's in-house one.
