The Secret Behind Bulova’s Date Codes

For over a century, Bulova has been a symbol of innovation and craftsmanship, producing timepieces that are as precise as they are timeless. Yet, beyond their stunning designs lies a hidden language: the codes etched into their cases, dials, and movements. These seemingly cryptic markings unlock the secrets of a watch’s history—its year of production, movement type, and its role in Bulova’s legacy. In this blog, we’ll unravel these codes, revealing how they tell the fascinating stories of Bulova’s journey through time.

One of the most distinctive features of vintage Bulova watches is their use of date codes. These codes, found on the case back, consist of two simple characters: a letter and a number.

Dating a Bulova watch from the period between 1875 and 1926 is extremely challenging, however, for watches produced in subsequent years, the manufacturing date is typically identifiable using a specific code.

From 1924 to 1949, Bulova used specific symbols on the movement to represent the production year:

From 1940 to 1949, Bulova ladies watches used a case serial number system where the first letter indicated the production year: A for 1940, B for 1941, and so on through J for 1949.

First Letter: The Decade
- L = 1950s
- M = 1960s
  N = 1970s
Second Number: The Year
- A single digitfrom 0 to 9 representing the
  specific year.

For example:

L5 = 1955
M8 = 1968
N0 = 1970

These codes are more than just technical details—they are a bridge to the past. They allow collectors to:

Date Their Watches: Pinpoint the exact year of production.
Verify Authenticity: Ensure the watch’s components are original.
Understand Rarity: Identify rare movements or models.
Appreciate History: Connect each watch to its place in Bulova’s legacy.

For enthusiasts, decoding these markings is like opening a time capsule, revealing stories of craftsmanship, innovation, and resilience.
