A new balance, complete?

I’ve got a nice old wristwatch that’s been lying waiting for a repair.  The movement is a CYMA 162, it’s got a broken balance staff.  I did think that at some point I should have ago at trying to replace a balance staff, I have a good staking set. But it seems that maybe this alone may not be enough to accomplish a good job. While browsing for other parts I came across a supplier who has, a balance, complete. That is how they describe it. What would that usually consist of? Just the wheel,  hairspring, cock included?  I can contact them after the weekend, but for £25 I might save myself some grief and just buy a new one.

In theory this should be a drop in replacement, but...

1. Make sure you don’t get confused between shockproof and non shockproof variants... they have different balance staff lengths

2. I have bought supposed balances complete where the terminal curve on the hairspring wasn’t properly formed.

However, I would agree this is your best option

      Setting lever spring

      By RichardHarris123 · Posted

      I'm assuming that every time you set the watch you are work hardening the detent spring, maximum hardening is  where it meets the plate due to maximum deflection.   That's why it snaps there.  The Young's modulus may be the same but after it's reached its maximum yeid strength it breaks.  My mechanic engineering is very rusty, correct me if I'm wrong.

      Ah ok yes that makes sense to polish it where the arm starts to form from the body of the bridge, i thought you meant the underneath of all the arm.

      Epilame / Fixodrop

      this is something I've never quite understood about the some of the Swiss companies. In 1957 Omega was using 9010 for the keyless parts with epilam. there's been a slow migration towards using heavier lubrication's but still typically oils and epilam to keep them in place. When it seems like 9504 works so much better.

      Is this a 'hack' ?

      OK, welcome in the world of alarm clocks... I guess the 4th wheel is dished because it is from another movement. If it was not dishet, then it would not mesh with the pinion of the escape wheel, am I right? The marks of wear on the 4th wheel pinion doesn't corespond to the 3th wheel table position, at list this is what i see on the picts. Calculating the rate is easy - there is a formula - BR = T2 x T3 x T4 x T5 x 2 /(P3 x P4 x P5) where T2 - T5 are the counts of the teeth of the wheels tables, and P3 - P5 are the counts of the pinion leaves. Vibrating the balance is easy - grasp for the hairspring where it should stay in the regulator with tweasers, let the balance hang on the hairspring while the downside staff tip rests on glass surface. Then make the balance oscillate and use timer to measure the time for let say 50 oscillations, or count the oscillations for let say 30 seconds. You must do the free oscillations test to check the balance staff tips and the cone cup bearings for wear. This kind of staffs wear and need resharpening to restore the normal function of the balance.

      Any tips to correct a sloppy error?

      Glue a nut to the barrel lid, insert a bolt, pull, disolve the glue.  Maybe someone will have a better answer.
