The Miyota caliber 2035 is a quartz movement with 0 jewels. This 3-hander caliber is a true no-date (no phantom date crown position).

Movement markings: No Jewels / Unadjusted / Miyota Co. / Japan

The 2035 was introduced in 1981 and celebrated its 40th anniversary in 2021. That is quite remarkable, for a quartz movement to still be in the manufacturer’s current catalog after four decades.

“The de facto standard in the industry, the Caliber 2035 debuted in 1981, the year after the Miyota brand was launched. With a total of five movements developed based on Caliber 2035 in that same year, including a calendar movement and a two-hand movement, the history of Caliber 2035 began.” –The Birth of Caliber 2035

The 2035 is a record breaking watch movement. In March of 1999, the caliber 2035 was featured in the Guinness Book of World Records for manufacturing 1,769,593,600 units of the 2000 series calibers worldwide since September 1981 when it debuted.

As of this post, Miyota says they have produced more than 5 billion caliber 2035 movements (source), with at least one movement made every second. The movements are still made in Japan at the Saku Factory, which Miyota touts as one of the world’s largest watch movement factories (and just one out of the company’s 17 factories).

Similar Calibers:

Previously, there was also a caliber 2035 with a “Super” designation. The Super 2035 was listed at having a higher accuracy (+/-15 seconds/month) and longer battery life (4 years). It also featured a gold tone finish and a coil cover.

The caliber 2036 is almost identical to the 2035 with the major difference being that the 2036 is a high hand version. High hand movements allow more clearance between the movement and the hands, giving more options for the dial design.

Other similar movements include:

  • 2035G – gold plated
  • 2025 – no central seconds hand
  • 2034 – disc seconds hand

Interesting note: The official instruction manual for the cal. 2035 is shared with the calibres 203A, 2033, 2036. and 2039.

Accuracy Rating:

Miyota states the accuracy of this 2035 movement to be +/-20 seconds/month.

Power Reserve:

The 2035 has a battery life of 3 years. This movement also has a hacking function which can serve as a power saving feature. Pulling out the crown/stem to time setting position can reduce the power being used if you’re not going to wear the watch for a while. Be careful storing your watch with the stem pulled out!

Crown/Stem Removal:

Miyota calibers such as the 2035 do not have an arrow to indicate the location of the release button for stem removal. There are several peg-like shapes sticking out of the movement that appear to be buttons, but they are actually there to hold parts of the movement in place. Instead, you will be looking for a small indentation, which you will press down with your tweezers to allow for the stem to be released. Follow the video below:

Replacement Prices:

At the time of this post, prices for the caliber 2035 quartz movement were found online around $5.95. You can order replacement movements here.

Replacement/Repair:

Although the 2035 is a metal movement, it is typically considered to be a replaceable movement in the watch community. This is mostly because the cost of the movement is low enough replace with a new one. However, before going that route, it’s always worth it to check the coil conductivity and potentially replace it rather than the entire movement. This would also save time and hassle since you wouldn’t need to remove the hands and install them on the new movement. Coils can usually be found individually or in packs of 10. Even if you do buy a new movement, it might be worth it to use the coil from the new movement first before swapping the movements completely (just be careful not to damage the new coil).


2035 Assembly/Disassembly Video:

Fake 2035 Movements?

It appears that there are indeed fake 2035 movements on the market. The made in China versions may work just as well as a genuine 2035, but for about $10 more, you can find a real one. Prices for the “replacement” movements were found for as low as $1.61 USD. Amazon even sells 2 for $7.99.

A wonderful piece of engineering. Just be sure that the crown is pushed in before pressing down on the release when removing the stem.

could you, please, explain about the 7T35 caliber ?! Is this caliber genuine movement from Miyota?!

7T35 is Citizen’s number I think. Same as 2035. 7T35 is interchangeable with Miyota 2035. Citizen makes Miyotas. You’re all good brother.

Also used in fake Enicar watch that says Automatic on dial face and stamped on back of case. This watch must have cost about $2 to $3 to produce as it sells for $10.00.

Can these replace a Seiko Y121E? Are the hand post diameters the same? Thanks.

Why not just use another Seiko Y121? My cheap “George” Walmart $8.88 watch has one, and is now just 6 seconds fast after 3 months!

I used the Miyota 2035 to replace even cheaper Z618 Chinese movements. The Z618 were slow and the minute hand jumped with the second hand. The 2035 was a perfect fit but wondering if there is a Swiss equivalent to the 2035.

I have a watch I inherited and it’s almost the same movement as the one above but it has 1 jewel with silver oxide cell 364. I don’t know if it’s worth refurbishing. I don’t even know if it runs but does need a battery of course. And the watch itself is degradated some sort of pot metal casting. What do you think? Toss it or not?

Such an unsung hero! Totally awesome, cheap, reliable, easy to keep going, also easily replaced, even repaired if needed. However: ”It is considered a replaceable movement.” ..? I guess you meant to say its cheap and plentiful enough not to be worth repairing/servicing? Other than that it is actually a FULLY REPAIRABLE METAL CONSTRUCTION watch movement, leaving behind a good number of other japanese and even many swiss entry-level quartz movts.

Hi! Good job on the update, such a pleasure once again (as your writings tend to be). This great little movement has been on so many of my watches over the years and recently I found them on Casio MRW-200H (the minimalistic AQ-24 also uses them) and really love their solid performance and apparent longevity and easy repairability. Recognising and celebrating their 40 years of success is what they truly deserve.

This movement has no date complication so I don’t think that it can be used in a Casio MRW-200H You may be confusing it with the Miyota 2035?

Yes, I mean to say that the whole range of this Miyota 2xxx-series is awesome, whether it is built with or without a date/day-date/moonphase/some other complication. You are right, each variant has its own designation.

Yes, You are correct. I didn’t mean to come across as pikky. The 2xxx series is absolutely amazing. They are so cheap on Aliexpress that I have spare movements for all of my Casio analog watches and I have never replaced one of them yet. I even fitted a 5R21into an Omega Deville ladies watch in place of the original ETA movement. I was quoted $123.00 for the ETA and I paid $10.00 for the Miyota and it keeps excellent time. My wife corrects the time approximately every 3 months.

I received this movement from aliexpress. Seems like this is the fake one that is mentioned in this articale. It doesn’t say unadjusted. Rather it says Miyota, Japan, CWMJ. Another thing I noticed is that the long connecting pin right of the quartz is plastic (marked)

It is quite a decent movement IMHO. I have it in my Rdunae RA03 (US Vietnam War era field watch homage) and I cannot be more satisfied. I love the watch, it is a very small one compared to the today’s standards (34.5mm case width and 41.8mm lug to lug). It fits perfectly on my 16cm/6.3inches wrist. I’m really happy that Rdunae choose a true no-date movement for the watch, as I hate date and also ghost date watches. The simpler the better for me – that’s why I love field watches. On AliExpress they stated that the watch has… Read more »
