SEIKO Chrono SAEK003 Automatic Watch

SAEK003

Overview

The Seiko Brightz Ananta SAEK003 is a 45mm men's automatic watch with a stainless steel case and a black analog dial protected by sapphire crystal. It uses a 8R28 caliber self-winding mechanical movement that can be manually wound and hacked (the second hand stops when the crown is pulled out). It ticks 8 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 45 hours when fully wound and will self-wind when moved.

The SAEK003 is currently ranked #402 in popularity out of 1,128 watches in this catalog. Check availability on Amazon.com. There are two model numbers for this watch which indicate different distribution locations, a different band type, or different text on the dial. The alternate model number is SRQ005. This watch is part of a family of seven 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.

SAEK003 is only a partial model number. [learn more]

The case of the SAEK003 measures approximately 45mm wide (not including the crown) by 15mm 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 screws down to help prevent it from being accidentally pulled out while under water. The watch has a display back to show of the 8R28 movement.The stainless steel bezel shows a tachymeter and is fixed (cannot be rotated). The gap between the lugs is 22mm and the leather band can be removed using a band removal tool to be replaced with another band.

The SAEK003 provides the following features and complications:

  • Second hand
  • Seconds subdial
  • Minute hand
  • Hour hand
  • Chronograph that includes subdials for hours and minutes with a minimum resolution of 1/4 second and a maximum duration of 720 minutes. The central second hand is used by the chronograph. When the chronograph is not in use this hand is stationary. Seconds are shown on the seconds subdial.
  • 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.
