Boluva Watch - Dated 1952 - Model number: 120103 (can not find what model this is) - Case number: L-269287 - Waterproof - Stainless Steel - Purchased in Birmingham England, 15th November 1968
This being a UK purchased watch, we will likely label it as an 'International' model.
We have limited information for watches outside of N.A.; and the only item I can find for something similar, based on that 120103 model number is from one 1960s International Pricelist. These watches just show a model number, no name.

We will date it to 1968 based on that sale date; but, the movement would be the key to dating it. The case may also have a datestamp on the inside.

That's great thank you! The back of the watch is stamped with the model number that makes me think its a 1952 watch. It seems that the watch was re-boxed when being sold again in 1968. I am hoping to get the back of the watch off this week to date the movement.

You're welcome. This watch would be from the mid sixties or later. You will likely find a two-digit datestamp inside, look for an M#. Movement is likely a model 11ALC or 11BLC.
Agreed, this one should be dated by the sale date and similarities to Line Book listings until movement confirmation can be made. I am good with tentative
1968 International
Welcome to myBulova, this is nice classic looking Bulova. I think watches sporting this style case back design are Swiss (Bienne) models. As Ken stated above, our catalogs don't contain names for these watches, only reference numbers. We generally classify them as "International" models. I've updated the year to 1968 as it's most likely closer to the year of manufacture than 1952. Thanks for sharing it!
