SEIKO Diver 6105-8000 Automatic Watch
Overview
The Seiko 6105-8000 "X237" is a 41mm men's automatic watch with a stainless steel case and a black analog dial protected by hardlex crystal. It uses a 6105 caliber self-winding mechanical movement that cannot be manually wound but can be 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 32 hours when fully wound and will self-wind when moved.
The 6105-8000 is currently ranked #217 in popularity out of 751 watches in this catalog. No retailer link is on file for .com; current availability is unknown. 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 6105-8009. This watch is part of a family of two 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 page. By clicking the checkbox under a similar model you can compare that model with this one side-by-side. We use nearly 100 different weighted criteria to calculate which models are the most similar to one another.
The case of the 6105-8000 measures approximately 41mm wide (not including the crown) by 13mm thick and is water resistant to 150 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 19mm 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 6105-8000 provides the following features and complications:
- Second hand
- Minute hand
- Hour hand
- 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
