What the Specifications Tell Us The listing states a quartz movement — battery-powered and regulated by a quartz crystal, the most widely used timekeeping technology in watches. Accuracy figures, if any, are the manufacturer's claims.
Ownership context: quartz watches run on a battery, and replacement is a routine service event rather than a repair. Timekeeping consistency is the movement class’s main selling point.
The manufacturer lists 200m water resistance. HardWatches has not independently tested this rating.
The case measures 40mm and is constructed from stainless steel, per the listing. The listing specifies a stainless steel strap. The crystal is specified as mineral crystal. Finishing quality — brushing, polish, and clasp feel — cannot be assessed from specifications alone; the product imagery on the listing is the best available evidence for it.
What this means for you: buyers comparing sport watches typically weigh movement type, case size, and water resistance first, then price and customer ratings. Those figures are all published data, shown in the technical table on this page and on the listing.
