What reviewers and owners say
Reviewers
From 3 reviews we read or watched, 1 of them with a watch supplied by the brand.
Reviewers liked the finish: horizontal brushing that runs from the case onto the bracelet, polished chamfers and a solid, well-made bracelet and butterfly clasp. All three noted that the clasp has no micro adjustment. One reviewer found the screw-and-pin links very hard to resize, while another found the link system secure and straightforward once understood, and one disliked sharp ledges on the clasp. Two reviewers found no lume on the dial or hands, and one found the pale dial hard to read in some light. Two reviewers found it wears longer than 38.5 mm suggests because of the 48 to 49 mm lug to lug, while a third found the integrated bracelet makes it sit smaller than that figure. Reviewers describe the design as following the Audemars Piguet Royal Oak, with some also seeing Grand Seiko, Nautilus or vintage Seiko influences.
