I strongly recommend using one of the RWI SV's for watch repairs otherwise RWI can't offer support to you if you send your watch, parts, money and things go wrong unless they are a listed Supporting Vendor.
Check the list of SV's for watch repairs/mods here on RWI. I'm from the Carolinas and I use misiekped in NY. Always top notch reliable service. There are many more on the list, see which one is closer to your location.
