Smith Cal 602 Calender spring

[Whatno]

Hi I’m working on my first project watch had a few problems mainly with the click spring on the train bridge. I am looking for a Calender ring spring can anyone help me.

[oldhippy]

What cal number is it?

[AndyGSi]

Yes, what cal is it as the 602 doesn't have a date.

Edit

So it looks like a 612 but no look with parts at the moment.

Smith parts are like rocking horse poop, which is why i buy just about every Smith watch i come across

Hi guys. All I know is there is Cal 602 on the movement. This is the first watch I’ve worked on so I am really at the beginning of the curve. I have brought a packet of springs from Maddison’s of Durham which seems a good place but there isn’t one exactlay matches. I have bought some small players and cutters plus a pin vice to try and modify one with mixed succes.

Ive got both the 612 and 602 spares let me have a look and see what we have going on. Back in 10.

So it seems the 602 was used either with or without the calendar works depending on the dial variation. Due either to manufacturing decisions or a watch guy choice to swap the movement for whatever was available . I'll go with with the factory as i have more than the 2 examples i show . No they aren't for sale , smiths are my main watch passion, so you better be quick with your ebay finger because I'll be right alongside side you bidding for a donor.

So yes the 602 is set up for a dial date complication. The 612 i will look into for the difference. 

I'll pull the spring later today when i have more time, will give you a pattern to work to, i may actually have matching springs in my stock. If i have I'll send you one if not I'll make you one, close enough to work with.

[Whatno]

Thank you very much I appreciate it. I’m starting to get a feel for this

[Neverenoughwatches]

Apologies for the late comeback,  my memory is terrible these days, I'll drag that spring out while i remember and see what i can help you with.

You're in uk i assume you mentioned 50 quid in your intro. 50 quid to change a 2 quid battery, i need to set up shop

i can see the spring for the date ring in your photo ?  Is this one that you've modified ?  Was the original one missing ?

This is the spring, pretty basic shepherd's crook, let me know what you're looking for.......and if you say a busty blonde.....then its too late i already have the perfect match

And no its not Sam Fox that we keep seeing in the lingerie ads at the top, mine is far better.

Hi I’m really struggling to get this bridge install over the gear set whilst stopping the click springpinging out. I have managed it twice but I can’t seem to perfect tbe skill. I can spend hours fitting the spring into the recess turning it over and aligning tbe gears but failure. I’m thinking there’s is something I haven’t seen but it’s so difficult to get this in. It’s an Ingersoll Cal 602. I’m running out of donor springs and the ones I change from other click springs don’t seem to be accurate enough and are worse. I’d love some help here. Regards Andrew

Have you tried pinning it down with a piece of rodico?

Yes I’ve tried that but there’s so little of the spring sticking out.

A suggestion...

Why just not assemble without the spring and put it after all is assembled (without the screw or whatever goes in the hole)? Not that I have tried - never touch such movement, but it seams like it is meant to be done as I say.

I'd thought the same thing but it looks like the click would be in the way when the bridge is fitted?

Edited November 9, 2024 by AndyGSi

Seems to me that it will get in, but let OP make a try.

[RichardHarris123]

Couldn't the side that doesn't move be glued? 

[Neverenoughwatches]

Did you get the date spring sorted ?

[Whatno]

Hi yes, I’ve sorted the date spring that’s fine it’s just the click in the bridge. The spring in the image is upside down. The spring fits into the little recess under the bridge so virtually impossible to fit after the bridge is in place unless it works by just being trapped with the screw. Yes, I even thought about fixing it in with a spot of glue but is this “ Cheating”.

[RichardHarris123]

An alternative is to make a clip to hold it in place.

Yes. I have had one fitted ok and the click has to drop over tbe lock ratchet which is so difficult.i have seen so many donor movements so I’m thinking there must be a thing I haven’t seen.

[Neverenoughwatches]

When i go home I'll take another look, i cant remember it being difficult.  I would suggest you increase the tension of the spring within the recess so it holds better.....open out the spring.

Hi, I’ve worked on that and it’s so easy. I assembled the gears and the bridge screwed it all down and then slid the spring in behind the  gear lock. Once I’d push the spring in as far as it would go I took the screw out and push the spring a bit further so I could see it then I put a fine needle in the hole to pull the  pin across. The great thing is it kept the spring located in tbe recess. Putting the mainspring in and tbe gears, bridge and click spring took me 20 mins. I’ve been trying this for weeks on and off. I never even lost tbe spring. Thanks again. I can’t believe I didn’t see this but I didn’t think there was enough room. That’s the difference between knowing what you’re doing and an “ Old starter” . Thanks again.
