Seiko 4R36 Movement Review – Which Watches Use It
Hello everyone, today we’re doing a Seiko 4R36 movement review followed up by a list of some of the most popular Seiko watches that feature it.
The Seiko 4R36 is a popular movement that appeared around mid-2011, some consider it to be a better movement than that found in cheap Swiss watches.
This was a pretty big deal at the time as people were looking forward to the idea of relatively affordable watches now being equipped with a quality Seiko movement that could be manually hand wound and hacked.
Variations of the Seiko 4R36 movement that you may have also heard of include the 4R35, 4R37, 4R38 and the 4R39. For information on all these movements, I recommend this Seiko support page which has been used as a reference for a lot of this article.
During this Seiko 4R36 review we’ll be taking a look at the capabilities of the movement including the speed, accuracy, and a number of jewels as well as extra features like if it has a day/date function.
Seiko 4R36 Review And Specifications
The Seiko Automatic 4R36 is a popular self-winding automatic movement that’s now found in a huge range of Seiko watches including the Seiko 5, Seiko SAR, and various Seiko Diving watches.
Features of the 4R36 movement include manual hand winding and hacking. But what is hacking?
A hacking movement stops the second hand when you pull out the crown to the time setting position, this allows you to set the time to the second. It was originally a military term.
Note that movements without a hacking feature can’t stop the second hand like this.

Seiko 4R36 Movement Accuracy
I wanted to keep this section on the Seiko 4R36 movement accuracy separate from the rest of the specification details as it’s a question commonly asked so I wanted it to be a bit more prominent.
The Seiko 4R36 beats at 21,600 beats per hour giving it a 6 beats per second movement. When worn daily on the wrist for at least 10 hours and at a temperature range of between 5°C and 35°C the Seiko 4R36 movement has been shown to be between +45 and -35 seconds per day accurate.
How To Set The Time, Day And Date Of The Seiko 4R36 Movement
Below I’ve included a simple diagram provided by Seiko watch that displays how to operate the Seiko 4R36 movement.
If you take the information provided in the crown operation abilities section whilst using this image you should be able to easily adjust the movement to your needs.
Again full details for the operation and care of the Seiko 4R36 movement can be found in the link provided. There would be no use in me rewriting something that’s already been done so well with plenty of useful images included.
