- "Evolution Of The first Successful Industrialized Watch" as chronicled in Origins of the Waltham Model 57. This presentation assumes audience is familiar with the History of the Waltham Watch Company.
- The (lowly) Broadway, last grade in the Model 57 series.
- Despised by collectors. Only saving grace is that it looks like a Civil War era watch, although it was made 10 yrs. later (1876).
- No key guard on winding square.
- Regulator index engraved on plate.
- Sprung under balance, nickel.
- No Fogg's center safety pinion.
- YET, sold more Broadways per production year than any other M57 grade. Paved the way to the success of the A.W. Co.
- I'm still looking for the last M57 made, probably a Broadway around serial number 1,300,000.
