Rotary Seamatic Strap 300 Automatic Watch - GS05430/88

This 42mm dive watch features a polished 316L stainless steel case with a screw-down crown protected by a crown guard, delivering solid construction for underwater use. The blue dial carries applied indices in varying shapes with luminous coating, paired with open hour and minute hands finished in white. A black ceramic unidirectional bezel sits above, whilst sapphire crystal protects the dial. Water resistant to 300 metres, the watch is powered by a Miyota 8215 automatic movement.

The utilitarian aesthetic continues with a silicone dive strap, chosen for its durability and comfort in aquatic environments. This straightforward approach to sports watch design prioritises function over ornamentation, making it suitable for both casual wear and genuine diving activity.
