I purchased a used breitling chrono superocean A13340 a month ago. watch is in great condition. was originally purchased in 2009. Since i got watch it has been losing 10 sec a day which i know is off spec. but this past week it has started to lose 7 sec a day instead of its usual 10 sec. What makes the watch lose less time/speed up? watch has been kept on winder since i purchased it. i have wore it 3 times. will it keep losing less time/speeding up? is something off on watch?
any info will be appreciated.
