The NH36 sounds like an upgrade over the NH35, but the higher number does not mean better accuracy, a longer power reserve or a faster beat rate.
The real NH35 vs NH36 difference is much simpler: the NH35 displays the date, while the NH36 displays both the day and date. Both movements have 24 jewels, a 21,600-vph frequency, manual winding, hacking seconds and more than 41 hours of power reserve. Your decision should therefore depend on whether you value a clean date-only dial or the additional convenience of seeing the weekday.
One calendar value · cleaner dial
Two calendar values · more info at a glance
- Choose the NH35 if you want a straightforward automatic movement with a date display and a less crowded dial.
- Choose the NH36 if you want to see both the weekday and numerical date at a glance.
The TitanPro 300M's NH36 sounds like an upgrade over the AbyssPro 1000M's NH35, but the higher movement number does not mean better accuracy, more power reserve or stronger performance.

There is a 0% difference in jewel count, frequency, published power reserve, outside diameter and movement height. The calendar display is the only major buyer-facing difference in their official headline specifications.
What is the NH35 movement?
The NH35 is an automatic mechanical movement supplied by Time Module for use by external watch manufacturers. It uses the movement of the wearer's wrist to wind its mainspring, although it can also be wound manually through the crown.
Its display includes:
- Hours
- Minutes
- Central seconds
- Numerical date
Pulling the crown into the time-setting position activates its stop-seconds device, commonly called hacking. This stops the seconds hand so the watch can be synchronized more precisely.
The NH35 is particularly suitable for someone who wants a dependable, easy-to-understand automatic movement without an extra weekday display. Its date-only configuration also gives watch designers more freedom to create a cleaner dial. For a full breakdown, see our NH35 dive watch guide.
What is the NH36 movement?
The NH36 shares the NH35's principal architecture and headline performance specifications but adds a weekday display alongside the date.
It offers:
- Hours
- Minutes
- Central seconds
- Day of the week
- Numerical date
- Manual winding
- Hacking seconds
At the crown's first setting position, the day and date can be adjusted separately by turning the crown in different directions. The exact arrangement can depend on the movement configuration and how it is installed in the watch.
The extra day wheel makes the NH36 more informative, but it does not make it more accurate or powerful. Buyers should treat it as a functional alternative to the NH35, not as a higher-performance movement.
What is the main NH35 vs NH36 difference?
The NH35 displays one calendar value: the date. The NH36 displays two: the day and date.
That means the NH36 displays 100% more calendar information:
more calendar information — but not 100% more performance.
(2 − 1) ÷ 1 × 100 = 100%
This is a useful functional comparison, but it must be interpreted correctly. It does not mean the NH36 delivers 100% more performance.
Both movements still have:
The NH36 simply adds one more piece of information to the dial.
NH35 vs NH36 movement accuracy
Both the NH35 movement accuracy and NH36 movement accuracy are published at approximately −20 to +40 seconds per day under specified testing conditions.
The full published range spans 60 seconds:
A movement consistently operating at either limit would produce the following mathematical results:
| Period | At −20 seconds/day | At +40 seconds/day |
|---|---|---|
| One day | −20 seconds | +40 seconds |
| Seven days | −2 minutes 20 seconds | +4 minutes 40 seconds |
| 30 days | −10 minutes | +20 minutes |
Real mechanical accuracy can change according to regulation, temperature, resting position, activity, state of wind, shocks and component wear. One individual NH35 may run more accurately than another NH35, while a well-regulated NH36 may perform substantially inside its published range.
- Therefore, buyers should not expect the NH36 to keep better time merely because its model number is higher.
Power reserve and frequency
Both movements provide more than 41 hours after being fully wound under the specified test conditions.
That is approximately:
- In practical terms, the movement can run for one full day plus approximately 17 additional hours. Because 41 hours equals roughly 85.4% of a 48-hour weekend, a watch removed on Friday evening may stop before Monday morning.
Both movements also operate at 21,600 vibrations per hour, or 3 Hz. That produces:
This equals 518,400 vibrations per day. If the movement operated continuously for an entire 365-day year, it would complete approximately:
That is approximately 189.2 million vibrations per year. Neither movement has a frequency advantage.
TitanPro NH36 vs AbyssPro NH35
The two movements support very different watches in the Future Wrist Tech lineup.
| Feature | TitanPro 300M | AbyssPro 1000M |
|---|---|---|
| Movement | NH36 | NH35 |
| Calendar | Day-date | Date |
| Listed price | $199 | $199 |
| Stated water resistance | 300 m / 30 bar | 1,000 m / 100 bar |
| Case material | Grade 2 titanium | Stainless steel |
| Crystal | Synthetic sapphire | Mineral |
| Diameter | 43 mm | 46 mm |
| Thickness | 11 mm | 17 mm |
| Primary benefit | Lightweight daily utility | Heavy presence and stated depth rating |
- The TitanPro 300M combines its NH36 day-date movement with Grade 2 titanium, a synthetic sapphire crystal and an 11 mm-thick case. It is the more practical option for someone who prioritizes all-day comfort, calendar information and a slimmer profile.
- The AbyssPro 1000M uses the NH35 date movement inside a substantially larger stainless-steel design. It is intended for buyers who prefer greater wrist presence and a much higher stated water-resistance rating.
Who should choose the NH35?
Choose an NH35 watch if you:
- Only need the numerical date
- Prefer a cleaner dial
- Want fewer calendar settings
- Do not regularly check the weekday
- Are choosing a watch based on its overall build rather than extra complications
In the Future Wrist Tech range, consider the AbyssPro 1000M if you also want a larger steel watch with bold presence and a stated 1,000 m water-resistance rating.
Who should choose the NH36?
Choose an NH36 watch if you:
- Regularly use a weekday display
- Want day and date information together
- Prefer traditional day-date styling
- Wear your watch during work and scheduled routines
- Do not mind resetting two calendar values after it stops
The TitanPro 300M adds this day-date utility to a slimmer Grade 2 titanium case and sapphire crystal.
The NH35 does not give the AbyssPro its stated 1,000 m rating, and the NH36 does not determine the TitanPro's 300 m rating. Water resistance comes from the completed case system — crown, seals, crystal and construction.
Frequently asked questions
The main NH35 vs NH36 difference is the calendar. The NH35 displays the date, while the NH36 displays both the weekday and date.
No. Both have the same published NH accuracy range of approximately −20 to +40 seconds per day under specified test conditions.
No. Both movements provide more than 41 hours of power reserve after a full wind under the documented test conditions.
Not automatically. Although their core dimensions match, compatibility depends on the dial openings, crown position, day and date configuration, hands, movement spacer and case.
The NH35 is closely related to the Seiko 4R35 and offers the same basic date-only function, but they should not be treated as universally identical in branding, components or published tolerances.
The NH35 is better for a clean and simple date display. The NH36 is more useful if you frequently check both the weekday and date.
Time Module lists their country of origin as Japan or Malaysia. Buyers should not assume that every NH35 or NH36 was manufactured in Japan.
No. Water resistance comes from the completed case system, including the crown, seals, crystal and construction. The NH35 does not give the AbyssPro its stated 1,000 m rating, and the NH36 does not determine the TitanPro's 300 m rating.
