Seiko (TMI) NH36 Automatic Movement - Day Date (White)
$100 SGD - $150 SGD
The full-calendar workhorse.
Genuine Seiko NH36 automatic movement with day and date function, crown at 3 o'clock, with white 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.

Movement swapping is recommended only for individuals with the right skills and experience. Every movement passes Time Module Inc. (TMI) quality control before shipping and is guaranteed fully functional on arrival. Given the DIY nature of modding and Seiko's trade practices, movements cannot be returned once shipped.

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?
Customers praised this automatic watch movement for exceptional accuracy, with many reporting +1 to +5 seconds per day. The regulated version exceeded expectations, performing better than standard tolerances. Shoppers appreciated fast shipping, careful packaging, and excellent service. One customer noted "super accurate out of the box!" The movement is hackable, making it an affordable upgrade.
- Super accurate out of the box! Running at +1 spd!
- Accuracy was much better than Seiko tolerances, worth the extra money for regulated movement.
- The movement has kept time within regulation specs, about +5 sec/day which is even better!

I received the movement today and checked it on my timegrapher before installing into my SKX007 mod. Accuracy was much better than Seiko tolerances. For me it was worth the extra money to get the regulated movement.
