Movement Identification - Bovet

Recommended Posts

Hello

Does someone know what type of movement this is? It can out of a Bovet military watch but I don't think its a Valjoux or a Landeron. I haven't taken the dial off and looked on the other side of the movement.

Thanks in advance for any help that can be provided.

But i see a Incabloc spring. So must be shockproof . Never seen a FHF 70 with center second attachment? 

 Where?

Many variants to fhf70 with different bridge layout were made, namely inderctly driven min hand, then this with center second cock and your regular sweep second with min wheel incorporated inside ebauche. 

Its ancestor fhf30 and on, were mostly sub second versions.

Almost every manufacturer put some versions in their watches,  some were in-house and high grades , Rolex did too.

Thanks to everyone for their responses. You've been a big help. Here are two more pictures of the time piece I'll be servicing. The crystal more than likely will need replacing as will the stem. I can't put any power into the movement as the click won't sweep fully to allow the crown wheel to turn.

Questions:  1.) Does my watch come with a seconds hand? I'm not sure if it does or if it uses a sub seconds which the dial doesn't accommodate.

2.) Are all seconds hands sized the same? I don't mean the length, I mean the pinion that they are secured to on the fourth wheel (?), is it the same for all seconds hands? Hope that makes sense.

3.) I'm thinking of buying an assortment of ETA watch stems, will I find a stem that fits this movement or do I need to search for a fhf70 movement specific stem. 

4.) What is the best parts source for this movement; Cousins, Gleaves London? 

Thanks in advance for any help that can be provided.

There appears to be a seconds hand pinion in the middle of the minute hand hub, and the movement shows a cock and tension spring for a center seconds pinion.

No. You can measure the end of the pinion with a micrometer to determine the correct size.

No. You will need the correct stem for this movement, which may be common to other FHF calibers in the same family, but very unlikely to be common with any ETA stems. If there is enough thread left on the broken stem you could use a stem extender.

Cousins certainly seem to have a comprehensive stock of FHF70 parts.

You may need to get a more positive ID for the movement. Ranfft lists the FHF 70 as a sub-seconds movement but yours has a sweep seconds hand. It is definitely part of the same family as the 70, but some parts will differ from the sub-seconds 70.

Thanks very much for the responses. I believe the next step will be for me to dismantle the movement and have a look. I have a list of items I want to order from Cousin's and if I can figure out what I need from this watch then I'll include them in this order. 

Thanks

Hello

I've stripped down this movement and have noted the markings. Can someone please clarify the type of movement based on the photo I provide? Is it a FHF I75 (as is i75) or a l75 (as in L75). I'm also having a little difficulty in figuring out the size for the second hand. I measure the pinion (?) at .30mm (second picture). Does that sound correct? 

 

Thanks

    • Dell fancy a challenge🤣   https://www.ebay.co.uk/itm/285785684626?itmmeta=01HT29WVJY21Q94C73GYHGBTFX&hash=item428a277a92:g:15YAAOSwNRVmBAUz&itmprp=enc%3AAQAJAAAA0DIe4QLQBW66rSyIMiyBuk8GY%2B86pQ%2BQnxGbcNq7egAGe5DIs9YMmiWJIbZtMSxwNJIiJxuojbq523IeUSBQ6pJEIQ0tfz2ChrBR03BksmKINyklg1IK4GAfAcYY9Hta9wVeSZSZN7ZCNAfZTgKs9c4%2BUIUZ3Qjc3QjUXDn2uPRo1FiYOEewMG5A26EXb%2BclBgrqtbOmM6P3bea%2F8ZImOAXNI1HtbmtMk84pIGoM6ISwaM1PKFuADtTFMccS5e3ZjndCbXYXHrW3CecsV0edw3M%3D|tkp%3ABk9SR8q588nQYw Darwin’s theory of evolution has not been proven to be absolutely.  😀 
    • A already know the size movement I have the problem is the dial a had purchased has a dimension 20.6mm wide a want to find a watch case that going to fit the dial perfectly 
    • Hi.  I would like to take issue here regarding battery driven , watches, clocks,etc. I will and do repair these clocks in fact I have sever al in my collection as well as the regular mechanical ones. I have one on my mantle piece over 60 years old tha belonged to my wife’s Aunt,  long gone Iam afraid and it has been cleaned etc and never missed a beat and is accurate. Every one has their preduices as regards Electrical /electronic Horology but I regard it as part of the progress time line of the art of Horology and to be treated as such. Like Darwin’s theory of evolution it evolved.  Two cavemen knocking rocks together and a shard broke off , looking at it he worked out if it was stuck on the end of a stick he would have a spear. Likewise his pal seeing what he was up to picked up a piece  and did the same, now that’s evolution. Some clockmaker decided to build a clock that ran with a battery and no spring to wind up and break, progress and both the mechanical and battery driven clocks evolved, the battery ones got better to the point that if it broke you changed the complete unit. Likewise watches did the same but both can be repaired by people who approach Horology with an open mind without preduice.  We all have our likes and dislikes bu I for one would never dismiss any technology because I don’t like it.   The mobile phone is a good example of modern technology at work as is the automotive industry. There buttons and switches in my car I don’t use because to me they are not nesessary but I still drive the car.
    • I haven't gone through all the reading of what it might be or not. The first thing I would do if nothing obvious stands out is replace the mainspring, you have to start at the source of the power. Nine times out of ten that is the problem.  
    • Haha. You're just in a wicked mood today John 😅
