Measuring 42mm across, the round stainless steel case of this Royal Oak Offshore is fitted with a sapphire crystal and a stainless steel bezel, offering water resistance to 100 metres. The blue dial lends the watch a bold, distinctive character that has long defined the Offshore line within the broader Royal Oak family.
Power comes from an automatic movement, keeping the watch running without the need for manual winding. A stainless steel bracelet with a buckle clasp completes the ensemble, lending the piece a cohesive all-steel presence on the wrist.
Reference 25721ST.OO.1000ST.01 is a men's timepiece that balances the architectural heritage of the Royal Oak design with the more assertive proportions the Offshore series is known for — making it a compelling choice for those drawn to sports-luxury watchmaking.
