The movement is in working condition at the time of cataloguing. All functions are working. The calendar is advancing. The dial is in lovely original condition with all printing nicely raised in hard enamel which is clearly defined. The original finish of the dial has taken on a more ivory tone. The hands with only very light oxidation. The case is in absolutely exceptional condition with fluting to the lugs is extremely well defined and incredibly easy to see. There is a very crisp hallmark under the lug at 11 o'clock. There is a second hallmark underneath the case back and there is 18k stamp to the outside of the case back that is very easy to see. This is an exceptional example of the 2499 with a Vichet case that is easily to understand why it is sought after by collectors so much. The long downturn claw lugs and flat case back are really exceptional and give a completely new look to this reference. It is believed that there are less than 10 pieces known examples with a Vichet case and this watch is an absolute masterpiece. This bracelet is from the 70s and was a late upgrade to this historically important watch.
