The Seiko SND549 (7T92-0FW0) is a 42mm men’s quartz watch with a stainless steel case and a blue analog dial protected by hardlex crystal. It uses a 7T92 caliber quartz movement. The watch should run for up to 3 years before needing a new battery.
The case of the SND549 measures approximately 42mm wide (not including the crown) by 10mm thick and is water resistant to 100 meters. This should be sufficient for splashes, rain, baths, showers & swimming (shallow diving) but is not recommended for scuba diving. The crown does not screw down which increases the risk that it could be pulled out accidentally while under water. The stainless steel bezel is fixed (cannot be rotated). The gap between the lugs is 20mm and the bracelet band can be adjusted to fit using a link removal tool but may be difficult to replace with another band due to the shape of the lugs.
