I found these prices in general
Average
price Guide.... ( prices can change, please inquire)
Average cost for Automatic overhauls $285 -$349 (7-10 days)
Average cost for manual vintage $185 (7-10 days)
Average cost for Battery Changes (Swiss Watches) $49.50 (2 hours)
Average cost for Battery Changes (Japan Watches) $10 (15 minutes)
Exterior detailing ($75 - $125) - Scratch removal - polish or satin finish like
new (1 day)
But specifically found a price of about $250 for an overhaul of a Quartz/manual. But generally they never mentioned replacing the quartz mechanism.
It seems that the original $139 was for a service and a battery which a combination of the above prices. If you add the replacement cost of the quartz and all the work being done via Ebel it seems to add up.
Sorry to drag on.
