Just back from being professionally serviced 8/5/2018. Sorry about the glare in the pictures off of the crystal. I have wore it for the last 10 days. Runs smoothly and keeps accurate time. Has a 10k gold filled case with a textured finish to the bezel as shown. Case measures 40.19mm (lug to lug) x 34.57mm (does not include the crown). Longines marked crown. Date feature to the dial. Clean dial and hands. Has a "Hi-beat" (36000 bph) movement with 17 jewels. Wonderful vintage condition. It is monogrammed with a "G.B." to the back. No pictures of the movement will be provided. I do not like to remove the case after service. Here are the reference numbers and description of service provided by the watch tech:
