What reviewers and owners say
Reviewers
From 7 reviews we read or watched, 2 of them with a watch supplied by the brand.
The reviewers called it good value for a 200 m quartz diver. They praised the clicky 120-click ceramic bezel (most found no backplay; one noticed a tiny bit), the strong lume, the sapphire crystal with its AR coating and the compact shape. Several measured it at 43.5 to 43.7 mm across the case, 47 mm lug to lug and about 11.9 mm thick. One reviewer who compared it with the brand's automatic version found the quartz one 1.6 mm slimmer.
The weak point they name is the bracelet clasp: five say it is a pressed metal clasp rather than a milled one, though two found it solid and one found its edges acceptable. One reviewer found the inside faces of the lugs sharp, and one said the polished bracelet sides scratch easily. Three reviewers received the watch from the brand or were given a discount by it.
