SEIKO Diver SNZD77 Automatic Watch

SNZD77

Overview

The Seiko SNZD77 (7S36-02E0) is a 42mm men's automatic watch with a stainless steel case and a orange analog dial protected by hardlex crystal. It uses a 7S36 caliber self-winding mechanical movement that cannot be manually wound or hacked (the second hand does not stop 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 43 hours when fully wound and will self-wind when moved.

The SNZD77 is currently ranked #266 in popularity out of 751 watches in this catalog. Check availability on Amazon.com. This watch is part of a family of three watches that are identical except for their color or strap. You can see the other variations in this family as well as other similar models on the left side of the pagein the similar watches section below.

SNZD77 is only a partial model number. [learn more]

The case of the SNZD77 measures approximately 42mm 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 stainless steel bezel shows minute numbering and can be rotated. The gap between the lugs is 22mm 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.

The SNZD77 provides the following features and complications:

  • Second hand
  • Minute hand
  • Hour hand
  • Day window to show the day of the week including two language choices for the day (English and either Spanish, Arabic, Kanji, Chinese, French, German, Danish or Roman Numerals). When setting the day keep turning the crown to get to the next language. On most models SUN will be red and on some models SAT will be blue.
  • 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.
  • Rotatable bezel
