What's Your Opinion Of This Movement?

[WillFly]

I'm currently looking at a watch which has 21 jewels and a double-ringed beryllium balance. The dial is very nice, but I've not seen a movement like this before.

 

What might be the point of the balance design, do you think?

 

Cheers,

 

Will

Never seen one like that...  whats the front like?

[atimegoneby]

I've never seen one either,  just a guess.... could it be same weight / inertia as a larger balance wheel but a smaller compact size ?

Not seen one before either Will, but I think it would be a bit of a bugger to work on as there appears to be no separate bridges.

Thanks for the comments - appreciated. I just don't see the reason for the beryllium balance and, as you say, it could be a bit of a devil to get into. Here's the full eBay listing:

Nice dial, though...

[PadraicB]

Dial has something interesting, it notes "Jemaflex". A google search later, and it appears to be a method of adding flexibility to the balance wheel as shock protection for the pivots. Apparently related to Wyler's Incaflex. Stab in the dark but turns up often as a comparison.

It looks like some of the jeweled pin-pallet movements I've worked on, especially the fact that there are no separate bridges which makes aligning the drive wheel pivots so much fun you'll be curled up under your work desk in the fetal position--trust me, I know.

Indeed! I can't imagine that parts will be easy to find either...

[anilv]

The 'hammer'ed finish, lack of shock protection and unsigned movement (not branded) fail to impress. Also if you count the jewels in the top plate.. there seem to be 5 wheels.. the one under the 't' in twenty looks like the escape wheel so what are the 2 capped jewels?

 

Basically this was from the dark ages of Swiss watchmaking...

It is a very nice curio movement! Never seen this balance wheel solution before either!

[Geo]

I'm with Anil on this one, not keen on it at all. :-(

[WillFly]

I'm not touching it!

I have had one or two of these berrylium balance movements, Buler produced one and I have another in my spares of similar design...

Hi. I have the same Buler beryllium balance movement, working great but I am looking (Buy?) for the glasses

The purpose of a watch's balance structure is to regulate the measurement of time. This is an important part that oscillates back and forth at a constant rate for the watch to display the correct time. The design of the balance also plays a role in impact resistance and durability, ensuring that the watch will withstand the wear and tear of the wearer's daily activities. After all, a well-designed balance wheel is essential for a watch to function properly and maintain its accuracy over time.

I've seen them and repaired them. they are not that wonderful, the finish is something a bit on the poor side.
