SEIKO 5 SRP609 Automatic Watch
Overview
The Seiko SRP609 is a 45mm men's automatic watch with a stainless steel case and a blue analog dial protected by hardlex crystal. It uses a 4R36 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 SRP609 is currently ranked #150 in popularity out of 2,613 watches in this catalog. Check availability on Amazon.com.

The case of the SRP609 measures approximately 45mm 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 a pilot slide rule 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 or removed using a band removal tool to be replaced with another band.
Transform the look of this watch by adding a 22mm leather band such as a Hadley Roma, Hirsch or Crown & Buckle.

- 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).

- 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.
