SEIKO Diver 6306-7000 Automatic Watch
Overview
The Seiko 6306-7000 is a 44mm men's automatic watch with a stainless steel case and a black analog dial protected by hardlex crystal. It uses a 6306 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 40 hours when fully wound and will self-wind when moved.
The 6306-7000 is currently ranked #385 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 6306-7001. 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 6306-7000 measures approximately 44mm 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 screws down to help prevent it from being accidentally pulled out 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 or removed using a band removal tool to be replaced with another band.
The 6306-7000 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
