Seiko (TMI) NH36 Automatic Movement - Day Date (Black)
$100 SGD - $150 SGD
The full-calendar workhorse.
Genuine Seiko NH36 automatic movement with day and date function, crown at 3 o'clock, with black wheels. A popular upgrade from older 7S26/7S36 calibers, adding hacking and hand-winding alongside the full day+date calendar.
Two accuracy grades. One genuine Seiko caliber, QC-passed by TMI.
Pick Regulated for watchmaker-tuned precision, or Non-Regulated for Seiko factory spec. Every unit is a genuine Time Module Inc. movement, tested functional before it ships.
Day and date together.
A full calendar complication: day-of-week plus date, both quick-set. Crown out one click to correct day and date, two clicks to hack and set the time.
Regulated or non-regulated.
Choose Regulated and a certified watchmaker tunes it to 0 to +8 seconds/day before it ships. Choose Non-Regulated for factory-default accuracy of -20 to +40 seconds/day per Seiko's spec. Same movement, your call on precision.
Hacking and hand-winding.
Both built in. The seconds hand stops when you pull the crown for precise time-setting, and you can manually wind it. The popular reason modders upgrade from older 7S26/7S36 calibers.
In every box.
Each movement ships with a full-length threaded stem and a dummy stem with plastic crown. Additional full-length threaded stems are available separately.
How the NH family compares
| Caliber | Complication | Crown Position | Version |
|---|---|---|---|
| NH34 | GMT + Date | 3 or 4 o'clock | White |
| NH35 | Date | 3 or 4 o'clock | Black White |
| NH35 | Date · 6 o'clock dial | 3 or 4 o'clock | Black White |
| NH36 · THIS MOVEMENT | Day + Date | 3 o'clock only | Black White |
| NH36 | Day + Date | 4 o'clock only | Black White |
| NH38 | Open Heart (no date) | 3 or 4 o'clock | View |
| NH70 / 71 / 72 | Skeleton (no date) | 3 or 4 o'clock | NH72 |
Most NH movements fit either a 3 or 4 o'clock crown — the stem threads either way and the date disc isn't affected. The NH36 is the exception: its day wheel is pre-aligned for one crown position, so pick the standard (3 o'clock) or the 4 o'clock version to match your case. Every caliber shares the same 24-jewel automatic platform, 21,600 vph beat rate, and 41+ hour power reserve. Click any version to go straight to that product.

Questions, Answered
Everything worth knowing before you build.
Which dial does the NH36 need, and will an NH35 work instead?
Why does the NH36 come in 3 o'clock and 4 o'clock versions?
What's the difference between Regulated and Non-Regulated?
Is this a Type M or Type L movement, and does it matter?
Can I return a movement if my mod doesn't work out?
NH34 vs NH35 vs NH36 vs NH38 vs NH70 — what is the actual difference?

I have number of Seiko watches and have over the years purchased number of NH36 movements to replace original 7Sxx movements. I hate no hacking functions. Movements arrived double quick time (I’m in Australia). I wound them up and put them on time grapher. Both movements met the 0+8 second spec. I was bit surprised with the beat error at 1 msc than again I’m not a professional. Gray service. Have bought stuff before.

Looks great. I’m only using the date onto a Black Dial. The date number really stands out.

I want one of these for a 4 o'clock crown, do you have that day wheel version?
Hello Kevin!
Thanks for expressing interest in our mod parts!
Sorry, I do not have 4H day wheel version NH36 because it was never manufactured. All NH movements are all directly from Seiko are only 3H, they do not manufacture NH movements in 4H day wheel version (https://www.timemodule.com/en/product-and-download.php?ds_product=2).
Given Seiko does not manufacture NH movements in 4H, if you want to use NH36 movement as 4H, you have to either separately source directly a 4H day wheel, or procure a 7s26 and remove the day wheel from it. Thereafter, swapping the original 3H day wheel on NH movement with a 7s26 4H day wheel. This is literally your only option.
There are several youtube videos that demonstrates this swap.
Hope this helps. Let me know if you have any more questions.
Cheers,
Adriel
S
Are the day and date wheels glossy or matte black?
Hello Edolph!
Thanks for expressing interest in our mod parts!
Seiko only makes them matte black. If you do see them glossy, they are counterfeit movements.
Hope this helps. Let me know if you have any more questions.
Cheers,
Adriel
