Serviced October 2020, day and date complication, Swiss made automatic movement, 36,000 BPH, quick set date, near mint black dial with applied hour markers and painted minute track. Hand polished stainless steel case, stainless steel screw down case back, acrylic crystal, alloy mainspring.

Made from 1973 and 1974, the Hamilton Auto Date Dorchester comes with a Swiss made, ETA based, Hamilton caliber 625 automatic movement. Aside from the incredible aesthetics of this mid-70's era watch, the most intriguing feature of this watch is the movement that beats at 36,000 beats per hour. With a beat rate almost double that of most other vintage movements, the white second hand sweeps very smoothly across the dial. The watch features a near mint condition black dial with silvered applied hour markers and orange and white painted minute track. The day and date window is at 6 o'clock, adding to the outstanding 70's styling. The day and date are quick set. The NOS domed acrylic crystal was installed during service October 2020. The stainless steel case and bezel have been hand polished and shows some scratching. The stainless steel case shows some fine scratching consistent with age but also still has the factory brushing. The watch comes ready to wear on a two piece black leather strap with silver tone buckle. The 625 caliber automatic day/date movement was serviced October 2020 and is running well and currently performing at +/- 10 seconds per day.
