Hello there

. A newbie here with few Mechanical collection in hand. Hope can share and learn more from this forum.
Am also sort of like need help and don't know which section to post.
I have an Omega Speedmaster Mark IV, that is recently sent to service due to the following:-
1. Problem with the Chrono, which sometimes stop after awhile when use where you have to shake the watch and it will continue timing the crono again (Was told there's a drop in the bpm when the chrono was used by the Service Centre)
2. Changing the bezel (due to dent/mark) with an after market bezel found in ebay (similar but there are slight notable difference).
3. Polishing.
The watch are sent to TSC Amcorp Mall. The issue at hand is the cost for doing all this. Was quoted
RM1900 for the 3 things above. Damn I could get myself a Tag F1 for that price.
What do you all think. Is it fair/alrite or should I go to Omega service centre and get it done there. Will it be cheaper?
Thanks you all
