Why doesn't AP send their watches for COSC testing.

[noahjiawei]

I am new to this brand and recently got an AP. while looking at my Rolex, I realized its not chronometer certified. Anyone can tell me why?

When you are part of the "Holy Trinity of Watchmaking" and "Haute Horlogerie" why would you??? Regardless of the lack of COSC certification the accuracy of AP is always within standards. My 15300 is typically within COSC standards at +3-4 seconds a day.

Only 3% of Swiss Watch production is COSC certified.

Therefore, some of the ″Haute Horlogerie″ Swiss Watch Manufacturers have created on 5 June 2001, ″The Fleurier Quality Foundation″ to establish new aesthetic and technical criteria dedicated to the certification of finished watches. Their certification meets a normative requirement for the market and the final customer to have a better definition of quality watchmaking, adapted to today's demands and technological advances.

Rolex submit by far the largest number of movements to COSC followed by Omega SA, Breitling, TAG Heuer and Panerai.

My "COSC" Panerai is running really fast while the non-COSC AP runs perfectly, have not adjusted the time in 3 months :)

Totally agree love Panerai, but always adjusting to correct time.

I am far from an expert on the matter, but my Diver and Safari remain spot on..at times it blows me away how consistent they are!

I haven't adjusted my AP in 8 weeks, and probably won't do it for another 8-16 weeks. I do adjust wife's sub every other week though.

My GMT is slow, my Datejust is fast, my AP is SPOT F*IN ON!!!!!

Wow! Thank you so much! You blew me off with this information!

My 15300 is spot on when I leave it OFF my wrist. However, when I put it on, it runs fast...at least +30 seconds /day. I am going to leave it off my wrist for a few days as Submarino suggests to see if it adjusts to within the range of COSC standards. From what I've read, it's possible that sitting on the shelf too long before i purchased it may require some 'break in period'.

are you kidding me..?? AP owners dont wear APs to tell time !!lol....jokes aside COSC didnt appear before the 70s (correct me if im wrong) but some of the older watches keep times great...so i wont really worry about whether its COSC standard...ive wasted enough time in my life on some BS..guess losing/gaining a few minutes wont do me no harm...
