What reviewers and owners say
Reviewers
From 3 reviews we read or watched, 1 of them with a watch supplied by the brand.
All three reviewers found no back play in the bezel; two called the action tactile or lovely, and one said it is not the most refined but good for the price. Two called the short 46.8 mm lug to lug the reason the 43.8 mm case wears smaller than it reads, and two liked the bronze with the black dial; one showed the patina developing after three months and another praised the C3 lume.
One reviewer paid about 113 USD, below the current price. One found the supplied suede strap thick and stiff at first. All three named an NH35 as the movement; the brand page says 8215 in one place and NH35A in another, so the movement is not stated here.
