Hi everybody.

I took up learning watch repair a month ago, using the online courses from TimeZone Watch School and just finished building an ETA 6497-1 movement. I'm interested in British watchmaking and now plan to start buying up old Smiths movements with a view to learning about them and repairing them.

I look forward to getting involved with the forum.

Regards

Darren

Hi Darren, welcome from another relative newby! From the tags it looks like you're in HWyc? I'm not far away if that's the case, Twyford for me. Sounds to me like you're a man with a plan. Looking forward to seeing your progress with the Smiths movements. Any reason you chose Smiths?

Hi there,

Im interested in Smiths due to them being the last fully-inhouse watch manufacturer in England. The only people doing that now (as far as i know) are Roger W Smith...and you'll pay 100k for one of their watches ! Really interested in comparing how the Smiths Cheltenham factory build movement vs how ETA do it today.

Thanks for the welcome !

Welcome Darren. Here's something I posted a while back that you may find useful:

"Smiths produced clocks & watches from 1851 eventually opening a factory in Cheltenham producing the high end watches equal to the Swiss such as the Deluxe, Astral & Imperial ranges. The factory closed in 1970. Also a factory in Ystradgnlais, Wales, originally & joint venture with Ingersoll (not the American one) producing lower end pin levers such as the Smiths Empire & Ingersoll Triumph range & eventually a jewelled lever used in the Streamline range (see here: http://www.watchrepairtalk.com/topic/3157-smiths-streamline/). The factory closed in 1980. In the final years before closure movements were sourced from the Swiss & the Far East.

Smiths Group plc is now British multinational diversified engineering business with is headquarters in London, operating worldwide but unfortunately no longer produces watches.

The Smiths watch name is now owned by Timefactors who produce homage watches in small quantities with Swiss & Japanese movements.

Robert Loomes uses highly modified Cheltenham Smiths movements in his range, but you will need to save very hard to buy one."

Hope this helps. Smiths are easy to work on being designed for hand assembly. The only downside is they are getting increasingly expensive to purchase.

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