Hi all,

This is my first post. I did introduce myself briefly a few weeks ago. Just to repeat, I am a complete novice at watch repairs and very much on a learning curve. I have encountered a problem whilst tinkering with an old Sekonda watch with a Raketa Calibre 2609HA. I've stripped it down for cleaning etc including the mainspring. I have managed to rewind the mainspring back into the barrel with a mainspring winder (winding in a clockwise direction). When I came to replace the arbor I realised that the spring was the wrong way round.

Am I correct, is the spring lefthand in this calibre? If so is there an easy remedy because left hand winders don't seem readily available.

I would appreciate your advice.

Thanks.

Regards, Richard

Hi Richard, your easiest bet is to hand wind it.

Having said that, the last left handed I wound using a right hand winder. Fit the spring onto the arbor and locate on the case of the spring winder. Now start winding slowly and feed in the spring with your other hand instead of pulling it in with the winder alone. If you are careful you will be able to feed it all the way into the winder, then fit the spring into the barrel as normal.

Give it a try and let us know how you get on.

Get yourself a large steel or brass washer, big enough for the hole to be slightly smaller than the inside diameter of the mainspring barrel.

Wind the mainspring into your winder, left handed or right handed, it doesn't matter.

Install the mainspring into the hole in the washer.

Transfer mainspring from washer to barrel as you would a new mainspring.

Save yourself a fortune by equipping yourself with a good selection of large washers.

Thanks very much everyone for the ideas and comments. I have tried the washer idea and I've gone from thinking in terms of saving for ages for a three figure Bergeon something, to completing the task easily, quickly and very cheaply. It was a great idea, thanks Marc, much appreciated. 

Regards Richard.

      Replacing crystal, do I need a bezel tool?

      By Kalanag · Posted

      From what I see, the crystal is made of mineral glass and is secured to the bezel with a sealing ring. If you might want to replace the crystal without removing the bezel or the movement, I think it's possible, but risky. You have to suck out the old crystal without breaking it into tiny particles. I would not do that. If you remove the movement first you can press the crystal out and press a new one in without removing the bezel.

      New hobbiest to watch repair from the Netherlands

      By Sebastiaan · Posted

      Hello Everyone, A short message to introduce myself. I'm Sebastiaan (50) from the Netherlands and have always been interested in watches. My two kids are at the end of their teens years and so I have more time to start a hobby.  Working on watches was something I always wanted to learn. So I recently started the watchfix repair course. Currently watching level 3. My short term goal is to be able to service the watches we (Myself, my wife and kids) own. I own a manual Omega Geneve from 1974, a small microbrand watch with a NH35 and a wittnauer bumper from 1940's. My wife owns an Oris, Seiko 5 with 7s26c and my son a seiko alpinist sarb017 and sports 5 with 4R36. So enough to learn on the short term..  Looking forward to talking to all of you and enjoying the watch hobby together. Greetings Sebastiaan

      Longines with 25.17 caliber

      It works quite well. The only strange thing is that it loses 2/3 mn per day whereas the measurements indicate that it is fast by 1/2 mn. Maybe something wrong with the gear mechanism ...

      Unfortunate…but you clearly have a Longines branded movement with a year 1936 serial consistent with the caliber. I checked the case maker of the last few Longines I worked on… …same as your watch, so certainly you have grounds to honestly describe your watch as a Longines cal 25.17 tank with unbranded dial…and given the modesty of the watch IMO the Longines authentication wouldn’t dramatically alter the value, if that’s what you are hoping…as nucejoe suggests the value will mostly be determined by how well it runs…

      By VWatchie · Posted

      It's difficult to tell, but my guess is it just looks like it has a bezel. Once you have removed the movement, you should be able to tell. Either way, I think you should be able to press out the old crystal from the inside as long as you have a die that properly supports the area around the crystal. So, take it a part first and then assess if any additional tools or actions are needed. Let us know how you do!
