Have just put together an Certina DS-2 cal. 25-651 and the second hand work, but the minute and hour hands dont move. I can set the hands with the crown, the movment can be winded. But the hands dont move.
I have striped it once again, but I cant see any wrong with the movment.
Thanks a lot as always...... :-)))))
Can anyone help?
I have a NOS Certina C017.407A watch case and I need a 35mm DS Caimano dial but I have had no luck in finding where I can buy one. I have tried Cousins in the UK. Can anyone point me in the right direction? Ideally need a new or NOS dial or good second hand one. Movement wise the case will take Eta 2824 (2824-2/A2 etc.) & Sellita SW200-1
Thanks in advance for any help.
This morning I could pick my latest goody for my collection. A Certina Club 2000 from around 1968 in absolutely amazing unworn conditions. I don't dare to wear it!
I haven't checked yet but it is supposed to have a Certina 25-661 manual winding movement and of course it is a "Pre Hayek" Certina.
How easy is it to change the date wheel on a 2813 movement? Has anybody got experience, pictures of the disassembly or any tips to help me along the way? I know there cheap and throwaway but I'm doing a favour for a friend.
It's a bit hard to tell. Looks like the adjust wheel looks grimy tried to zoom the picture but it's a bit blurred. What I would do is put the stem back in and check the enguagement to see if it engages smoothly and isnt binding. Check the squared end of the stem to see if the corners haven't been rounded.
I have stripped down the movement completely and will check and re-assemble it tomorrow. Here's a pic of what the stem area looked like. Notice anything wrong ? I'm a newbie with quartzes so I certainly don't.
The additional jewels for the 24 jewels movements is for the auto winder, so shouldn't effect the loading of the gear train. The balances I believe are all the same, with some receiving additional adjustment for chronometer grading. I wonder if the GR reference is made from measurements of original springs fitted, and perhaps Omega updates them over time? Perhaps the metallurgy of the springs changed through the years, although all would be white alloy. The GR catalogue also quotes various springs for the Cal 26X range, but I believe these should probably all be the same. There's an argument that running a centre-seconds hand adds to the load (it will typically reduce amplitude by something like 5-10 degrees when adjusted) but that's not enough to significantly affect performance.
I see that on the Cousins website they list three different springs if you search for a Cal 565...
On my Cal 552 I have a 1.10 x .105 x 360 (11) spring which reaches 300 degrees amplitude, if that helps.
The watch has been returned to the customer. You are correct someone had been poking around with this movement most of the screws were very badly bruised the hairspring had been badly damaged & the balance staff broken.
