SEIKO 5 SRP148 Automatic Watch
Overview
The Seiko SRP148 (4R36-00D0) is a 42mm men's automatic watch with a stainless steel case and a gold 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 SRP148 is currently ranked #895 in popularity out of 2,613 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 SARZ002. This watch is part of a family of eight watches that are identical except for their color or strap.

The case of the SRP148 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 compass directions and can be rotated. The gap between the lugs is 20mm 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 20mm leather band such as a Hadley Roma, Hirsch or Crown & Buckle.

- Second hand
- Minute 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).
