The Seiko caliber 4R36 is an automatic used by Seiko Watch Corp. in their own branded watches. This movement was released circa 2011. This caliber was considered to be an upgrade from the popular 7S36 movement as it offers the user the desirable hacking and hand-winding functionality.

Caliber 4R36 VS SII NH36:

The caliber 4R36 is basically a Seiko-only version of the NH36. Seiko Instruments (aka SII) sells the NH36 to other manufacturers for use in non-Seiko watches.

Caliber 4R36 VS 4R35:

There is also a similar caliber 4R35. The different between the two is that the 4R36 has a day/date calendar complication at 3:00, and the caliber 4R35 only displays the date at 3:00. Everything else is the same, including dimensions, jewels, accuracy, etc.

Differences Between 4R36 and 4R36A?

The A indicates that it is the first generation of this caliber. 4R36 and 4R36A are the same, until Seiko releases a 4R36B which will be a second generation.

Accuracy Rating:

Seiko claims that the accuracy of caliber 4R36 is between +45 / -35 seconds per day. This rating is based on normal daily wear on the wrist in temperatures between 5 ºC and 35 ºC. When testing your watch for timekeeping, make sure it is fully wound.

Crown Position Functions:

0 (against the case): Clockwise = Manual Winding / Counterclockwise = Nothing
1 (pulled out one click): Clockwise = Day setting / Counterclockwise = Date setting
2 (pulled out two clicks): Time setting clockwise and counterclockwise

Stem Removal:

To remove the stem, make sure the crown is in position 0 or normal position (not date or time setting position). There is a lever with a small indentation for your tool. Gently press down while pulling the stem out. See official instructions below for more guidance:

Seiko Caliber 4r36 Stem Removal

Reply to  Michael Graham

You would lose the power reserve function, that aside you have to do some measuring because the stem height is a major factor in lining up your movement, dial fitting is another as dial dots are not very good so you will need to maybe get dial feet soldered or welded to the dial itself to get any decent hand fitment. Also the rotor height may be an issue if the YT is taller than the 4R, you can pack out a mm with a phat gasket but anything more than that will require some shaving of the rotor if… Read more »

From what I can tell, the hand winding get stiffer when its about fully wound, but if you wind the watch from standstill / low power state then it’s easy to wind it. I would only wind it if I haven’t been wearing the watch for 1 day or more, and I’ll stop winding once I feel the resistance is building up, and wear it so that the rotor can do it’s job.

If you can, you won’t be able to find one unless you pull it out of another Seiko. Read above it says this is seiko only, so what you need is nh36a. Search this site for nh36 or nh36a, maybe also nh35a. Good luck.

Hopefully someone can advise. In the past couple of weeks I got a Seiko 5 Sports SRPD51, really liking it. I noticed that the watch is exactly +3 seconds each day. I know that’s pretty good, someone told me I won the Seiko lottery as the dials are perfectly lined up too. Lol. I’m wondering if it’s worth getting it regulated to bring it closer to 0 or is that about the best it will get? Thanks in advance for any advice.

Maybe one more tip, if you are not wearing it 24/7 i.e. for sleeping as well. Then you can experiment with the positioning for overnight. The 6-8 hours of 24 while you are asleep is noticeable, and leaving the watch for those 6-8 hours face down, up, crown at 3, 6, 9, 12 hours, the notable 6 positions, might result the watch in losing 3 seconds while resting. And then it will be dead on.

Just saw these posts, and wanted to chime in:

If you place your watch on 3 or 9 o’clock position it will lose time while you are sleeping. Some watches lose while placed at 12 or 6 position. And the watches usually ‘gain’ time when resting on caseback or dial.

These are ‘general’ positioning effects on the accuracy, and they work on all of my watches such as Hamilton auto chrono, Hamilton mechanical, and all of my Seikos.

Give it a try and see how it effects the accuracy in your favour.

You can’t get +3 seconds per day, never! Probably if you would have chronometer. Why? Because, precision depends of how much is main spring is wounded, and also temperature condition, and also position of watch(balance wheel). Also, depends of if watch is brand new or much used…etc. How so? Balance wheel go arround itself about 240- even 300 degrees, depends of how much is main spring is wounded. So, if main spring is wounded fully balance wheel will achive more degrees, about 280°, but when a main spring is weak wounded, balance wheel will have about 230-240 degrees. So in… Read more »

I have a life hack that helps me always keep my Seiko SRPE65K1 (4R36) watch within -2/+3 seconds range without ever pulling out the crown to adjust the time. If I put the watch almost vertically with 12 pointing up, the watch loses 3-4 seconds overnight, which is about the same it gains during the day when I wear it. I discovered this trick a month ago by pure accident.

Yes, the watch moves differently in different positions, due to gravity, by observation and tests you can find out which position speeds up or slows it down. It is mainly for those who like to play and test…!!

The best I could get this movement regulated to is – 5 SPD while wearing. Positional variance is very high, so leaving it in various positions either gains or loses time in increments of 5 to 6 seconds. Hence a great shock resistant sport watch movement. I mainly use it as a beater. ETA 2824-2 and Sellita SW200-1 in their highest grade are my go to movements for time keeping needs.

You can’t get one of these unless you take one from a full Seiko watch. If you do, then do the math. Check what movement is in the SNKE01K1. Find it on this site. Check the size of diameter and thickness. Compare to this one. You also have to make sure Seiko kept the same dial feet location. Why do you want to change it though?

Hi all!!….I’ve got the PADI Diver version from new recently, and when I wind it manually it’s absolutely fine. However, I’m currently experimenting this evening with automatic winding, as I’m sure that yesterday it didn’t wind properly on its own, as it stopped at about 4am this morning. I only wear my PADI when I’m not working, so it only had about 3 hours of wear yesterday. As such, I’m purposely winding it on my wrist this evening, and I’ll let you know how it goes!!….

Absolutely you can. The other answer is incorrect. Since asking a similar question a, couple of years ago here, I got an NH36A on a microbrand watch (same movement exactly) to +2 spd. Yes, you CAN get it closer to zero. Sometimes you can even be lucky with a new watch with COSC level accuracy out of the box, but it’s rare of course. Still, any Seiko 35 or 36 movement can be regulated to high accuracy.

Hi all! I bought a SRPG27K1. I’ve been measuring the accuracy for 19 days now. It shows a +9.4 sec during this period. I did not expect such a watch to be this accurate. The watch has been on my wrist all the time. There was one day that showed +27.5 sec, and I got worried. But later it has stayed around +-1 to 2sec/day, and more often on the minus side. I can not explain the big advance one day.

Great results. My seiko watches get magnetised with ease due to the electronic gadgets and other tools I use. I like my Omega, and other Swiss watches which fight against magnetisation. Higher end seiko watches have a Faraday cage similar to Rolex to fight this problem as well as better shock protection.

Many things affect the accuracy of mechanical watches! For example, the watch will also get a rotating movement and restlessness will burn its rhythm, the temperature is enough to put the watch in direct sunlight, magnetism – if you put the watch on a cable or a reprak. it’s just mechanics and that’s why Seiko states that the accuracy of caliber 4R36 is between +45 / -35 seconds per day

It’s just that the breaking-in of the watch calibre has to be at least a month up to 6 weeks. Thèn you’ll be able to see it for what it’s fully worth. It’ll show you – most probably – that it can keep a daily +4 to 6 sec. per day over all. No worries, my watch friend @MF. 😀
