The Ronda caliber R150 is a Swiss made automatic movement with 25 jewels. This movement was announced at Baselworld in 2016. As a manufacturer of mechanical watch movements back in the 1960s, the R150 is not Ronda’s first mechanical caliber.

Ronda Mechanical Movements:

This movement is part of Ronda’s “Mecano 100” aka Series 100 line of movements. When the R150 was launched in 2016, there was talk of a full lineup of Ronda mechanical movements to come, however, at the time of this post in 2021, the R150 is still the only movement available in this series, and the only mechanical movement produced by Ronda.

In Ronda’s own words:

“The Mechanicals product range heralds the return of the Ronda Brand’s mechanical watch movements. The recently launched automatic movement R150 operates with a winding mechanism on both sides by means of a ball bearing. – “Ronda Mecano”, available exclusively as a Swiss Made line, is intended for premium timepieces.” –source

Ronda R150 VS ETA 2824-2:

Despite some misinformation online, the R150 is not an ETA 2824-2 clone. However, the R150 does share similar dimensions with the 2824-2: both are 25.6mm in diameter with roughly the same height (4.6mm for the ETA, 4.4mm for the Ronda).

Accuracy:

According to official documentation by Ronda, the calibre R150 is claimed to have an average accuracy rating of +/- 12 seconds per day with a maximum deviation of rate up to 30 seconds per day. Isochronism after 24 hours with +/-20 seconds per day. Ronda tests each movement in two positions at the factory. The R150 is equipped with an index system regulator for fine-tuning accuracy.

Ronda Caliber R150 Regulator

Power Reserve:

The power reserve of the R150 is about 40 hours when the movement is fully wound. According to Ronda, winding the movement by hand will reach full power reserve after ~27 winds. You cannot overwind the movement. In order to maintain constant running of the movement, Ronda recommends wearing the watch for 12 hours per day. When wearing the watch for fewer hours than 12, you may need to hand wind the movement a few times.

Swissness:

Ronda has a headquarters in Lausen, Swizerland as well as in Hong Kong. The Ronda R150 is labelled as a Swiss Made movement, but with the smoke and mirrors of the watch industry, it is not unreasonable to question how “Swiss” any movement actually is. For example, were all of the components made in Switzerland or only some of the parts plus assembly?

Replacement Prices:

At the time of this caliber listing, replacement prices for the R150 were found online in the range of $159.00 USD to $169.00 USD.

I remember when this came out 5 years ago and it was all the hype. The blogs were all talking like this was going to take over the 2824 and sw200. Now you can barely find any watches with this movement.

I’m eyeing the Aragon DF-42 these days. I originally wanted the black bezel + yellow dial but when I saw the blue bezel + blue mother of pearl dial, It’s to die for!! Too bad it’s no longer listed on Aragon’s DF-42 page…. The black bezel + yellow dial is Wing Liang’s personal favorite though, and that says a lot.

[…] The R150 offers about 40 hours of power reserve (although Ronda says that you will need to wear the watch at least 12 hours per day daily for the mainspring not to gradually lose the energy that it stores). It is fairly good at keeping time, too, with average isochronism after 24 hours of +/- 20 seconds per day [2]. […]

I personally think the SW200 is the best Swiss auto if price is the first criteria. I just got the R150 and it is running well. But, I have many SW200’s hat I’ve had for over a decade, and they are flawless as far as durability and accuracy. I honestly don’t see more expensive Swiss movements being any better, until you get into Patek.

It’s nowhere near the best. To include price is a difficult one because the SW200 is used in watches that are a similar price with better movements. Most ETA movements are better. Powematic 80 and Longines L888 which sit next to watches with the SW200 blow it away and make it look outdated, which it is. Even the SW300 isn’t as good as the above but will be found in even more expensive watches. Brands are only using these outdated movements because they don’t have access to anything better and don’t have the impetus to manufacture their own movement. Some… Read more »

We’ll have to agree to disagree. I own several watches with the SW200 and all are very accurate, very smooth seconds hand, and all have been reliable. Reliability and accuracy have been my criteria for watches and air rifles. I’ve had expensive that were good, and not as expensive that were just as good. You seem to be speaking of aesthetics, saying the SW200 “looks” outdated. It may be outdated in that sense, but as I look down at my watch that is always accurate, with the smooth sweep, I can’t see how outdated it is. Each of my SW200… Read more »

I didn’t mention aesthetics. It’s a common phrase to say “x makes y look outdated” when referring to different aspects e.g technology in this case. I’ll be sure to contact the Swatch group and tell them a guy that’s into toy guns said not to bother updating their movements because he is fine with the old one from a third party. I expect Tudor will follow suit and shut down their Kenissi factory in favour of gong back to Sellita.

My Orient F6N43 runs +21spd, and still within factory spec. One of the major shortcomings with Japanese workhorse movements is the unpredictable range of regulation. You are fortunate if your Orient runs +1.5spd, but it’s not typical. The +4spd in the Ronda likely is typical. And it’s likely more consistent in multiple positions.

It’s totaly and utterly normal, because it’s the main spring that glides through – over the notches which are on the barrel’s inside – so it can’t be overwound by it’s owners. 🙂 😉

I was reluctant to get a watch with this R150, but Aragon had a watch with titanium, tungsten and meteorite with this movement incased. I couldn’t pass it up! So, I’ve been timing it, and it is just a bit less than -4 seconds per day. This is very good! Since the watch is new, I don’t have long term info, but will come back in a couple months to add positive or negative.

Great! I love Aragon! The quality is on par with much more expensive watches, and this particular one has a great movement and is gorgeous. I haven’t seen a drop in accuracy, but since my initial timing I haven’t been paying as much attention either. I have at least 15 Aragon watches now and looking to get the Soprod M100 Hercules.

I used to buy Invicta watches. Then, I noticed slowly and with noticeability, the quality dropped off. Their “Reserve” was at one time “Swiss Made”, then they went to “Swiss Movement” but retained a pretty high asking price for being “Invicta”. I haven’t purchased an Invicta for many years now, and I wouldn’t recommend them to anyone.

Right. And it is within their listed specs. I do understand where he is coming from, though. You’d love to have an auto that times under 5 seconds +/- without paying thousands to get that. I have a Grand Seiko Spring Drive that is so accurate, it beats many quartz watches. After putting on another watch, you can’t help but be a little let down.

I have several ETAs, Sellitas, 6r15s yet Ronda R150 nowadays doing very well with +3 seconds in a day like an unspecified chronometer movement. Idk why that good, but it’s also up to regulation since Tüsenö did it very well. I’d love to see R150 caliber more in independent brands. And hopefully Ronda can introduce top grade movements in a near future.

Just bought A Schaumburg Watch with this movement.
Gnomonik No.1 – SCHAUMBURG WATCH
It is advertised as a Sellita movement, but I could read Ronda through the glass caseback.
Hard to say anything regarding accuracy (it lacks accuracy by design one could say 🙂 ), but it is quiet and the rotor seems a bit less responsive than a Powermatic80 (both new).

I own an Aragon DM 50 mm with the R150 from Ronda. First, I am a collector of over 72 watch brands ie; Tissot, Mido, Omega, Rolex, LIV, Ocean Crawler, Breitling, Tudor, Torgoen ,Formex, Seiko, Spinnaker, Longines, Venezianico, Direnzo, Boldr, Casio and Aragon. With all these different brands and movements and after testing all over the years, the Aragon Dive Master 50 mm with Ronda R150 has been the most accurate. I have measured +.01 seconds in 24 hours and amazingly consistent.

As of 2/8/2024 Invicta Stores is selling this movement R150 in their Swiss Made line in 46 and 52 mm for $119.90 US. I picked up this watch before it sold out. This is cheaper than the movement alone. Invicta’s retail brick and mortar stores went bankrupt. I’m guessing Invicta Stores online is liquidating their stock? I know this isn’t high end but at this price it’s a good every day beater. My best watch was an Omega Seamaster automatic I got at the PX in England in 1970 for $75.

Hi,

I am new here. I am just starting to go into movements and tinker with them. My experiment first is to replace a miyota 8200 movement. I only see 8205 on the site. I am guessing they are both the same except that the 8205 has hacking and the 8200 does not. Am I correct or is there anyone knows. My I have to put hands and a dial, it will be the first time trying. Any tips?
