What makes the Boston 423 unique: Today, we are thrilled to present this remarkable piece from the American Waltham Watch Company — the Boston 423. Originally manufactured in 1924 by Waltham, the Boston 423 features a stylish watch dial, gold type numbers, and an open-face back, revealing the intricate stainless steel gears with gold details. The subtle plainness of the dial accentuates the gold-type numbers, giving them a gradient texture. Powered by 17 jewels, our Machined Titanium case adorns this 1235-grade timepiece with an incredibly durable and scratch-resistant coating. Lastly, our Merlot leather strap compliments this piece wonderfully. This watch was originally produced in Waltham, Massachusetts, in 1924 — the same year that the History of Science Society was organized in Boston. It is the world’s largest society aimed at understanding science, medicine, technology, and their interactions with society.
