When timing I don't reset every day. When I reset it I write RS for reset. After reset I will try and write how long it ran for. If on time I will put OT down. If 1 minute fast I put +1. If the next day it does not lose anytime I still add +1 because it was not reset. If the time is way off I will write WO. If a day is missed I will write DO.Satisfaction guaranteed!

To help make the sale I could, With your request, throw in a few watch bands and/or batteries at wholesale price.
I graduated from the Bulova school of watchmaking in Oct 1978,
I got my certification from the Minnesota board of examiners in
watchmaking in 1981.

The Minnesota board of directors gave me a symbol to put on every watch I clean and overhaul.
This symbol is a rhombus with the letters BVS in it. I put the date the watch was worked
on near the symbol.

I worked for Fox Valley Trade Shop in Fond du Lac Wisconsin in 1979. Then JJ Smith in Janesville WI then Goodman's Jewelers in Minneapolis Minnesota then had my own watch repair place and now I own my own jewelry store and have since 1985.
