The Rotary Seamatic GMT is built for reliability whether you're exploring the depths or traversing time zones. Its 300m water resistance means you can confidently take it on serious dives, snorkeling, or any water-based activity without concern for water ingress. The robust stainless steel case and sapphire glass provide excellent protection against impacts and scratches, ensuring the watch maintains its aesthetic and functional integrity through adventurous use.
For travelers, the automatic GMT movement is a core feature. You can set the main hour hand to local time, the GMT hand to your home time zone, and use the bi-directional GMT bezel to track a third time zone. This makes it incredibly convenient for global navigation and staying connected across different continents. The black dial with its clear markings ensures readability at a glance, even in challenging conditions. The silicone strap offers comfort and flexibility, making it ideal for extended wear during activities or travel without causing irritation.
Unboxing and Initial Winding: Upon receiving, gently wind the crown clockwise about 30-40 times to initiate the power reserve of the automatic movement.
Setting Time and Date: Pull the crown out to its furthest position to set the hour and minute hands. Push it halfway in to adjust the date (turn in one direction) and day (if applicable, turn in the other direction). Avoid setting the date/day between 9 PM and 3 AM to prevent damage to the movement.
Setting GMT Hand: Pull the crown to the middle position (or as per specific movement instructions, consult the included manual). Rotate the crown to adjust the independent GMT hand to your desired second time zone. The GMT hand completes one rotation every 24 hours.
This watch features a 42.5mm case size and a 22mm lug width. It generally suits medium to large wrists. The silicone strap is adjustable to fit a wide range of wrist sizes, typically 6.5 to 8.5 inches in circumference.
Water Resistance: While rated for 300m, always ensure the crown is fully screwed down before any contact with water. Rinse the watch with fresh water after exposure to salt water or chlorine to prevent corrosion.
Cleaning: Clean the case and strap with a soft, damp cloth and mild soap. Avoid harsh chemicals. For the silicone strap, occasional cleaning will prevent dirt buildup and maintain its appearance.
Storage: When not wearing, store your watch in a cool, dry place, away from direct sunlight and strong magnetic fields. For automatic movements, consider a watch winder if you don't wear it regularly to keep it running and lubricated.
Servicing: For optimal performance and to maintain water resistance, it is recommended to have your watch professionally serviced every 3-5 years by an authorized watchmaker.
