Hello All,

I am looking for the following screws in gold colour,

Dimensions in millimetres
Head diameter
0.83 - 0.84
Thread Size
0.47 - 0.48
Length
1.57 - 1.58

I’m thinking of these ones Diagram 101 and 127

cousinsuk.com/product/bridge-screws-wristwatch-graded#

cousinsuk.com/product/balance-screws-wristwatch-graded

But I can’t find their thread and length other than reference to ‘diagram’

I would appreciate if someone advise/point me finding/buying them.

Thanks

Movement 

ETA 201.001

 

Calibre

9.9mm

 

SCREW, CELL CLAMP # 

X/12142 (54400/201.001) 

 

I found these two suppliers so far,

 

http://www.julesborel.com/checkout-2-05-0/cart.ssp?sc=3#cart

 

https://hovigs.com/products/battery-clamp-screw-x-12142

 

The estimate total cost for 5pcs is ~ €70 including shipping import tax EU

 

I would rather buy within Europe to cut shipping/tax expenses. Cousinsuk indicates it’s discontinued.

The part you've shown is a Ronda 726 screw. If you've searched 54400 then that's just the generic part no. for battery clamp screws.

The 51.600.01 is used across multiple ETA movements. (example 210.001)

I have checked part numbers in ‘Swiss part description’. Am I right assuming they are interchangeable to the subject one - same dimensions and colour?

If that’s so, than I found better price for ~£2.

Thank you Andy for the wise observation. I learn now that the movement/calibre ought match part number.

As mentioned earlier, sometimes the calibre can be different as a lot of parts are
used across them but the key part is the manufacturer which in your case is ETA.

Thank you Tom for the confirmation. I will go for 3 pack. Thank you Andy for the wise observation. I learn now that the movement/calibre ought match part number.

Hello Samy i hope everything is well on your end. I too am looking for the same exact screw that I saw you posted about me too for a chopard watch. Could you please let me know if you were succesful in finding one where you ordered it from and how fast the delivery was. Any advice or help in this matter is welcome. Thank you so much for your help

Hello @Tahagg

The identical screw is: SKU X/12142, 0 54400 / 201.001

I bought similar ones from cousins.uk: ETA21000154400, ETA 210.001 54400 as kindly suggested by @AndyGSi, but notice they are silver colour not yellow/golden, other than that I think they should fit, but I didn’t try. The delivery in EU is within 10 days.

I bought the identical screws - yellow/golden from US, hovigs.com *****@*****.tld. They’re are very nice to deal with.

    • Agreed, this is puzzling. Can you ask questions or inspect the lots before bidding? My Boley & Leinen Reform face plate is dia. 95mm exactly. It's possible that 4 inches is a slightly too large approximation, but why then make the distinction to 3 11/16 for the sake of 8mm? If the larger ones are truly 4" then they will clash with the bed, but then I have no idea which 8mm lathe would take them. All 8mm lathes have spindle height 50mm or less, as far as I know. The spindle height is, as you say, standard 50mm for W.W.
    • I have only been a member for six years & I have found this a very friendly forum although I don’t have anything to do with watches not because I don’t like watches but because I have gout in both hands so my dexterity isn’t very good, I restore torsion clocks & occasionally other antique clocks also at 72 my eyes are not what they used to be, that is why I only post on the clock forum & the lathe forum mostly . As others have said Mark it is much appreciated that  you are willing & able to do this. very many Thanks Dell
    • Ah, this is brilliant, thank you very much!
    • A local machinery auction this week is liquidating some watchmaker's equipment. Actually a truly absurd amount of it, from a machine collector's estate, making me wish I had waited a couple of months to buy my lathe because there are so many options at low prices. Anyway - there are a handful of faceplates on 8mm collet mounts up for sale and I think I can probably get one. Having never had one in hand, they seem kind of large as described though - all are listed at either 4in (101mm) or 3 11/16in (93.7mm) diameter. As I understand it, WW lathes are 50mm from spindle center to bed so it seems like the 4 inch faceplates would not have enough clearance. Could I expect the 3 11/16in to fit with a WW headstock and bed? What is a typical diameter for a faceplate? Also possible the description of "4 inches" is only a rough estimate by the auction house and not actually accurate. Example the 3 11/16": I may have answered part of this - a lot of the listings on ebay from typical American lathe tool makers are specify about 3.75 inch diameters. Still I don't see any that specify 4 inches, but I am still guessing that is an overestimate by the auction broker.
