10 Best Vintage Seiko Birth-Year Watches
November 17, 2018
It has been a long-standing tradition with any watch loving man to pick up or own his ideal birth year watch. The key is to get something that was manufactured or produced during your birth year.
There are others who would want a more specific down to the birth month and birth year (BMBY). But a lot would just settle for the birth year.
What are the usual brands do people go for? It would depend on the person though. If you have a lot of money to spend, then nothing is stopping you in getting a birth year watch from any of the top Swiss giants like Rolex, Omega, or even a Patek Philippe.
However, not everyone can afford to splurge on vintage Swiss pieces.
The key to a good birth year watch would entail the following:
-
Manufactured within your birth year
-
Comes from a watch maker with proven horology history
-
Functions and performs well or as expected (keeps time)
-
Contains all original parts (not a “Frankenwatch”)
-
Easily serviced when needed (if it breaks)
With this, Seiko would be the best reasonable and affordable birth year watch choice for any budget-conscious man. Seiko has been producing watches for more than a century hence their very rich horology history.
They can certainly be easily serviced and repaired. Best of all, can withstand the test of time in reliability and performance.
Quick Fact: How do you determine when a Seiko watch was produced?
For most vintage models, it can be seen by the combination factors of the movement caliber, case, and serial number. But for this document, we won’t be dwelling on that as I have already summarized the production date ranges of each of the watches below.
