But still most of the costs are public...
This is only my qualified guess and the offer you will get from the Manufacturer or AD. The guess is based on Patek's prices in Switzerland:
- Service for the movement SFR 800.00
- New crown SFR 85.00
- Polishing of the case SFR 120.00
- New case back SFR 1,800.00

Subtotal SFR 2,805.00
VAT % SFR 224.40

TOTAL SFR 3,029.40
The service of the movement can be more because the watch is over 20 years old. The price of the case back is also a guess but it's based on some experience.
I hope this helps. Anyhow, deliver the watch either to Patek or an AD in order to get an exact price. If you will decide to fix the watch, you will get a fantastic watch back in some 8-12 weeks after delivery.
Best, Kari
