I have a 1956 President (a black dial "B"). The crown is quite tired though and would like to replace it. Would someone have the reference number for this crown? 

Here's a picture of the crown I'm searching.

Hi Everyone,

I'm looking for a  day wheel for my 819 Caravelle. The movement is labelled 11 UOACB. I found a day wheel for an 11 AOACB.    

Will this work? What is the difference between the two calibres?

thanks

 unable to understand year of manufacturing and model. anybody can help me ? tks

When doing some research on a recent database addition it has come to My attention that We have a couple of models confused with one another. 

The  1929'ish Bulova 'WINDSOR' and the Bulova 'CROMWELL' 

Whilst both are very similar, there are subtle differences that distinguish the 2, I have brought this to light in the individual watch threads but it seems it missed the mark so I'll bring it here. 

The 'WINDSOR' ad is 1929

While trying to decode all the movement number (see other forum topic), I also started looking at the early model numbers that Bulova used for their ladies watches in 1922 to 1924. Typically these model numbers are a 4 digit number.

Looking at the many movements Bulova used in the early days, al having a serial number, I wondered if there would be a system behind the numbers. After putting the most used ladies movements in a spreadsheet and analyzing them with pivot tables, I found out that there is a system.

When l started collecting early Bulova ladies watches from the art deco period between 1922 and 1930, and got to learn about how to date them, I was surprised to find so few 1927 watches in the two main on-line databases of myBulova and Watchophilia. Of the total 380 ladies watches I could find, including the ones in my own collection, just 16 were from 1927. Looking at men’s watches, the statistics are not different: just 12 watches over a sample that must be almost double the size of the ladies watches.

Recently, we have been re-evaluating a 1925 Pater watch record which was reported to have a 19K 1/12 Rolled Gold Plate hallmark as part of the inside case back markings.  The watch owner didn't have a picture of the inside case back, so we sent a private message to confirm the gold content hallmark.



She wrote back, with confirmation of both the gold content hallmark, and case serial number being correct as entered in root record.

A lot has been said over the years about Radium and its ill effects, and how it relates to horology. Watchmakers typically have had to contend with a vast array of toxic materials, Cyanide, Trichlorethylene, Carbon Tetrachloride, Ammoniated cleaning solutions, both water and hydrocarbon based, Rouges and polishing mediums, and of course, Radium.

I recently had the opportunity to use a Geiger counter on a variety of test subjects, and the results have surprised me. 

So I was browsing the interwebs and came across this box.  We all know Bulova made watches and airplane instruments for the U.S. Military.  This is an ammunition can from that era.  It has Bulova stamped on the bottom.  Pretty cool piece of your into Bulova Military watches.

Wonder if Bulova was given these to ship watches or instruments in?

What do we think of this?
