Made for just one year in 1973, the Hamilton Day 'n Date 501HF was part of Hamilton's High Frequency collection. These watches beat at 36,000 beat per hour, giving the center second hand a very smooth sweep. This watch comes with a Swiss (AS) made automatic 631 caliber movement with day and date complications at the 3 o'clock position. The date has a quick set function by pressing the crown in to advance the day. This watch hacks and hand winds. The dial is excellent with a metallic blue field and silver outer track. There is little to no patina visible. The applied silver markers are excellent as is the blue chapter ring with white painted minute markers. The paint across the dial is in minty condition. The original painted hands are good, with a small chip in paint on the minute hand near the post. The watch is ready to wear on the original metal two piece strap. The clasp is signed. The Swiss (AS) made 17 jewel caliber 631 high frequency automatic movement was fully serviced February 2019 and is running well and currently performing at +/- 12 seconds per day.
