Monta actually regulates to +/- 7spd
I've had a Monta Triumph for about a year now, and during that time I've observed that it averages -6-7spd. In the past, I've read that Monta regulated their watches to +/- 5spd. I decided to look around on their website to see if they actually state this anywhere—they don't.
So, I sent them an e-mail about my watch and told them about the +/- 5spd references I've seen in the past, and they responded and said that they actually regulate their watches to +/- 7spd (which means my watch is running in accordance with their regulation tolerances). However, they did offer to regulate the watch under warranty.
This post isn't to complain about the accuracy of the watch (I think Monta could tighten up their shot group in terms of regulating, but that's a topic for another time) but rather to dispel the notion that their regulation is tighter than it is. I know it's a relatively minor difference, but it's worth pointing out to keep consumers informed.
All that said, I'm extremely impressed with Monta's commitment to customer satisfaction. I'm not going to be petty and send them the watch to be regulated, as it is performing within their tolerances. Nonetheless, the fact that they offered speaks volumes about the brand.
EDIT:
After continued observation, the watch actually loses up to 10spd sometimes…so I think this one will go back to Monta for a warranty regulation.

I've had a Triumph from around 2019. Loses around 10 seconds a day also.
I recently noticed my Noble has been running a touch slow and wondered if they’d be cool about a regulation under warranty. Need to do that soon! Hope you got your situation all figured out.
Monta mentions plus or minus five seconds a day accuracy in this link from three years ago. I wasn't aware they backed off those numbers. As an owner of three Monta, and someone who likes my mechanical watches to be really accurate, this is a bit disappointing.
