Wanted - 10BZ 2 Part Water Proof Stem

Submitted by DarHin on June 13, 2012 - 6:02pm

I think the Bulova part #'s are #16B for the male (crown side) and #16C for the female movement side. The length on my old female movement side is 9.88mm. My Bestfit catalogs don't list any stems for the 10BZ.

I want to thank John (JP) for taking the time to look through his stems and sending a few candidates. Unfortunately, none of them will work.

I can trade a crystal if you need one or $$$.

Thanks

Hi,

The 10BZ takes the same stem as a 10BOAC.

I hope this chart helps.

Thanks for this chart! (9 years later :) )

I've "Enhanced" it to make it a little bigger for folks such as myself who struggle reading small text.

No 11AL? I want the female part for my Surf King pop-out style watch.

Darren, I have an 11ACC female that is a little longer than 9.88mm and will send it to you. I need to know the correct tap size for the male to fit your crown. This is a large lot of stems I jjust got in with lots of Bulova stems both male and female but the 10BZ itself was not among them.According to the interchange charts the 11ACC will fit and the female is long enough so now all we need is to come up with the correct male. They are all long and can be cut to length.

Why didn't you let me know the last ones I sent did not work. I never give up on a project and this is one I wanted to see come to a happy completion on both ends. I love my crystal and it does make the Clipper pop.

I will be leaving early in the AM tomorrow(Thursday) but will have my computer with me and can take the case of stems with me and get the right ones out to you from my grandsons home. If you can PM me with the info I can wrap this up for you and we will both be happy.

Your Friend

Thanks to Mark & Timerestoration for the charts, they are a big help.

John,

Actually, after seeing the male and female combination stem on timerestorations chart, you did send me 1 of those for the 10BZAC and it does seat into the movement. My problem now is how do I make that work with my crown. It doesn't look like the male and female parts that I have (er, that my WATCH has) or that I'm familiar with. Oh, my crown is a tap 11.

Thanks

Gilt or white gold?? Can you send me a pic of the crown showing the side so I can see the thickness. I may have a tap 11 crown for it.

Many Thanks to Jeff for the split stem reference! one I did not have.

Below is a Waterproof Crown chart.

The Chart indicates the correct Crown as being #139 if Yellow or #339 if White.

Thanks guys. I have the original crown.

I need to know how the male/female combination stem works as shown in timerestorations chart above. How does the crown attach? It doesn't look like the 2 part stem that I'm familiar with which is what was on the watch originally and are shown on the same chart.

Darren,

I'm not a Watchmaker but will attempt to help.

The split stem chart below indicates You may need the 9.95mm Female stem (16C) combined with a .45mm Male post (16W)

The post appears to be non-interchaneable ?

 

* the above chart appears in Bulova Split Stem Kit # 23A for Water Resistant Watches.

Yes Mark I think you are correct. My female stem was broken so I think that could be why my 9.88mm was a little off. The post in your chart appears to be correct. It is VERY short. Thanks.
