H Moser Movements

[Rivazza]

Good morning all,

I've recently taken a liking to H Moser, specifically the Heritage Centre Seconds and the Streamliner Centre seconds. After reading several reviews and watching a few videos I can't seem to find how accurate their movements are. Are they at least COSC? Does anyone have any insight??

[huydoan]

yes, COSC. I've read somewhere about this.

When I bought my Heritage Centre Seconds (calibre HMC200), I could find no information about accuracy. I reached out directly to Moser and was told that the company regulates their movements to +9/-1 seconds per day, averaged over 6 positions. They are not COSC certified. My Heritage gains about 8 seconds per day, a little more as the mainspring reaches the end of the power reserve.

my streamliner centre seconds ran about +6 per day pretty consistently. i'll be honest tho i havent had very good timing for any of my watches, patek, rolex, iwc, jlc, AP, seiko. none ran within cosc standards out of the box. first one that did was my GO seaq last year.

I’d say a bit quirky. Ive had that basic movement in 3 mosers. On two of them I would turn the crown like 30 times to get it going. Then movement would stop. I’d tap the back glass and it starts again. Weird.

Thanks for the replies. Nice to know I'm not the only one who hasn't found anything definitive on the matter. Should've known I was going down the rabbit hole whenever I watched a few of Tim Mosso's videos and he didn't bring up accuracy. At this point, not sure it's a deal breaker but I'd kind of like them to at least be COSC. They are just so damn beautiful that it may just put accuracy in the backseat.

Bringing this up. Noticed that my streamliner rotor has a tendency to get stuck and not wind. It was missed by me early on because I often rotate my watches every couple days. Confirmed it gets stuck unless i repeatedly shake it back on track. I guess the tolerances are off. If i tap the back glass it makes the escapement spring start running, but just for a short bit. I can give it a full wind and get the rated power reserve, but the rotor doesn't cut it. The watch with die after a few dies.

I'm wondering if anyone else experiences this with the HMC200 movement. This watch was originally purchased 12/2020, so i'll be seeking a warranty claim.

My Moser Endeavour has a concept dial so it's practically impossible for me to measure its accuracy.

Never had issues with my HMC 200 pioneer regarding the movement. Runs about 7 seconds fast but I have no issues with that. Initially had a issue with the hands, but it was quickly and professionally resolved and never had an issue since. Most Brand’s are not doing COSC, pretty much included all of Richemont and Swatch Group. Besides Rolex, Omega and Breitling - no one else is actively doing it.

Same problem happened to me. However, i just started noticed it 2 years after my purchase date. I did not expect for a Moser in-house movement to get stuck like that.

with a concept dial ... doesnt matter

Same here. Average is +4.5s/day for the past 66 days. Sometimes 8+ s/day depending depending on activities

What was the problem with the hands?

As a data point, just picked up the H. Moser & Cie. Heritage Centre Seconds (March 2023) and put it on the timegrapher. She has a very impressive hairspring that reads 328. Impressive and strong!

On the timegrapher she was +6 seconds (averaged for positions). Ok, that agrees with many here. For the heck of it, I took out my decades-old and trusted compass. YUP, she was slightly magnetized.

So i demag'ed the timepiece. Timegrapher then said +2 seconds/day. On my wrist, worn for the past 24 hours, the H. Moser & Cie HMC 200 in-house movement is running +/-0 for the past 24 hours. Most impressive!

Congrats on that pickup Steven! Really like the aesthetic of that piece. As I know you can fire off some nice photos, would love to see a lume shot if you get a chance.

Edit: Just went to the website. The indices on that piece are epic! Ceramic infused with Super-LumiNova.

[enjoythemusic]

You're right, some epic lume shots online and it stays quite visible through the night. I'm a lume junkie and so the raised numbers really make this ⌚ stand out.

The movement decoration and attention to detail are spectacular!

[enjoythemusic]

UPDATE: She's been on bicycle rides, chillin' 'round the pool, while working on the car, etc. worn 24/7. All good, plus we're now on Day Four and she is (in total) +3.5 seconds. Great regulation H. Moser!

Love, love, love this timepiece

I'm guessing there is no readily available advertised spec because there's nothing particularly special about the movement's accuracy. Which is fine. I have no issues with that, so long as the movement is consistent and reliable.
