One of the Max bills i wear the least (27.3500 611) is losing time but
I've owned for maybe 6 years and maybe worn in for a month maximum total in that time
Get it serviced or sell to a hobbyist who wants to tinker? ETA 2824 service is £150+
I’m doubtful that would require servicing at that age. It’s more likely to just need regulating which is a ten minute job to do. For some reason, hairsprings exhibit an effect where there elasticity varies from new which can cause the rate to vary as they bed-in.
