What makes the Boston 431 unique: Today, we are excited to introduce this incredible piece from the American Waltham Watch Company — the Boston 431. Originally manufactured in 1922 by Waltham, the Boston 431 features a stylish watch dial, gold-type numbers, and a clear back, revealing the intricate stainless steel gears with gold details. The bricks of gold that outline the dial speak to the weight of history this watch has been through. Our Machined Titanium case complements the gold type numbers wonderfully and brings out the navy blue hands of the piece. Powered by 17 screw-set jewels, this 225-grade watch with our natural leather strap brings unity to this piece. This watch was originally produced in Waltham, Massachusetts, in 1922 — the same year that KQV-AM began its radio transmissions in Pittsburgh, PA. KQV was powered by 5,000 watts during the day, but to avoid interfering with other stations on 1410-AM, it reduced its power to 75 watts at night.
