The Rotary Seamatic is built to excel in demanding environments. Its 300m water resistance means you can confidently take it scuba diving, freediving, or swimming without concern. The robust stainless steel case and sapphire glass protect the watch from impacts and scratches, ensuring longevity whether you're navigating urban jungles or ocean depths. The automatic GMT movement is a key feature for globetrotters, allowing you to easily track your home time alongside your current location using the bi-directional bezel. For instance, you can set the main hands to local time and the GMT hand to your home time, making international communication and scheduling seamless. The black dial with clear markers ensures superior legibility, a crucial aspect during low-light dives or quick glances. The silicone strap offers a secure and comfortable fit, even when wet, making it an ideal companion for any adventure.
Winding: If the watch has stopped, gently turn the crown clockwise about 20-30 times while in its normal position to initiate power. The automatic movement will then be powered by your wrist's motion.
Setting the Time: Pull the crown out to the furthest position (usually position 2 or 3). Turn the crown to adjust the hour and minute hands to the correct local time. Push the crown back in completely.
Setting the GMT Hand: The GMT hand typically adjusts in an intermediate crown position. Pull the crown out to the first or second click (refer to specific movement instructions if needed). Rotate the crown in one direction to adjust the GMT hand to your desired second time zone. Ensure the main time is set correctly first.
Date (If applicable): Some models may have a date function. Adjust the date in a specific crown position, usually by rotating the crown in the opposite direction from the GMT hand adjustment.
With a 42.5mm case size, this watch provides a substantial presence and is best suited for wrists that comfortably accommodate larger timepieces. The 22mm lug width allows for potential strap changes, though the included silicone strap is ideal for the watch's intended use.
Cleaning: After exposure to saltwater or chlorine, rinse the watch thoroughly with fresh water. Use a soft, damp cloth and mild soap to clean the case and strap. Avoid harsh chemicals.
Water Resistance: Always ensure the crown is fully pushed in before exposing the watch to water. Do not operate the crown underwater. Though rated for 300m, avoid exposing the watch to hot water or extreme temperature changes, as this can compromise seals.
Strap Care: Clean the silicone strap regularly to prevent buildup of dirt and oils. Avoid prolonged exposure to direct sunlight or harsh chemicals that can degrade the material.
Automatic Movement: For optimal performance, wear the watch regularly or use a watch winder. Automatic movements generally require servicing every 3-5 years to maintain accuracy and water resistance. Avoid strong magnetic fields, which can affect timekeeping.
