Forties vintage Bertmar watch with day, date, and month display. The red calendar hand indicates the date, the numbers 1 - 31 are on the outer track, day and month are displayed in the windows under the 12 o’clock position. I am often asked how to set a triple calendar watch, To set this watch turn the hands well past midnight (say 6:30 am), it is important to be sure that the gears that change the date are completely disengaged to avoid damaging the mechanism. There are two pin push setting points on the right side of the watch, above and below the winding crown, the top one is for the month and the lower one for the date. To change the day the hands must be rotated 24 hours to advance one day. This collectable timepiece is in excellent working condition and is has recently been serviced by our watchmaker. Photos are not actual size of watch, it measures 32 mm across x 38 mm (lug to lug) and is fit with a new leather bracelet.
