SEIKO Diver SSA051 Automatic Watch

SSA051

Overview

The Seiko SSA051 (4R37-00F0) is a 43mm men's automatic watch with a stainless steel case and a black-gray analog dial protected by hardlex crystal. It uses a 4R37 caliber self-winding mechanical movement that can be manually wound and hacked (the second hand stops when the crown is pulled out). It ticks 6 times per second which gives the second hand a smoother movement than quartz watches which tick once per second. The watch should run for up to 41 hours when fully wound and will self-wind when moved.

The SSA051 is currently ranked #586 in popularity out of 751 watches in this catalog. Check availability on Amazon.com. This watch is part of a family of seven watches that are identical except for their color or strap.

SSA051 is only a partial model number. [learn more]

The case of the SSA051 measures approximately 43mm wide (not including the crown) by 13mm 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 watch has a display back to show of the 4R37 movement.The stainless steel bezel shows minute numbering and can be rotated. The inner bezel can be rotated using the second crown to adjust the compass directions. The gap between the lugs is 22mm and the bracelet band can be adjusted to fit using a link removal tool or removed using a band removal tool to be replaced with another band.

The SSA051 provides the following features and complications:

  • Second hand
  • Minute hand
  • Hour hand
  • 24 hour subdial to show if it is morning or night
  • Date window to show the day of the month. Note that some watches may be damaged if you attempt to change the date between 8:00 PM and 2:00 AM, in which case you should change the time to be outside that range first then reset the time after adjusting the date. Check your watch manual for details.
