What mistake did you make today?


Recommended Posts

This is where the joys of repairing watches & clocks comes in. I had many times when watch repairs became awkward. I would give it a rest and work on a clock. Trying to catch up was a pain in the ass so I would work overtime or on my day off. When I had my own workshop I was working all hours that God gave me. If you are repairing and its your hobby then you can do what you want when you want.

Arrgh....! It's past midnight now. I better quit while ahead.

I spent the whole afternoon and evening trying to take apart a Waterbury open Brocot escapement clock movement. 

I got this movement to practise on because I've never worked on an American clock. What a stupid design. It's totally watchmaker unfriendly.

I've captured the mainsprings with containment rings and removed plates with great difficulty. But I can't get the two great wheels off because there's another wheel in their way.

I'll probably take some photos tomorrow and seek help from fellow forum mates familiar with American clocks. 

Why can't the Yanks do things like the rest of the world? 🤬

I'd like to revive this thread with the tale of my recent descent into madness.

My friend asked me to service his '60s Longines Flagship. It had been sitting in his drawer for the better part of a decade as he wanted to start wearing it again. The crystal was yellowed and badly scratched, the stem had more rust than thread, and the watch would stop intermittently. No problem, I thought.

I ordered a range of crystals, a NOS stem, and fixed the centre wheel's tendency to rub on the barrel. Skipping forward a couple weeks, parts had arrived and I was delighted to see that the tension ring crystal fit the case perfectly. My problems began when casing the movement, though.

A movement ring is fastened to the movement with two tabs and rests in the case on a shallow lip. Above the movement ring, a brass tension ring shaped like a C is forced into a slot in the case to hold the movement firmly in place. Here's a picture from disassembly:

Although fiddly, the process of installing these components didn't raise any red flags... Not until I realized that the movement sits around 1 mm deeper in the case than I'd expect. This is obvious when looking through the crown hole -- the stem would have to jut out at an angle to fit into the keyless works.

Cue multiple days and several hours of fiddling and head scratching and, admittedly, some swearing. This small misalignment didn't make any sense, and I was starting to doubt my sanity.

Eventually, eureka.

I had picked up the wrong case from my drawer.

The case I had in my hands was for a Certina movement. Many stars must have aligned to mock me, because the crystal diameter for these two cases is identical to within 0.1 mm, and most of their internal features like lips and slots are very similar. If it weren't for the slight discrepancy in movement resting height between the two cases, I would've never realized that I had goofed up.

Lesson learned: stay organized. Label everything.

Take care OH. Drink plenty of hot tea and go back to bed. Hope it's not Covid. Monitor yourself.

I just recovered from another bout of Covid and it wasn't fun. There's another spike in the number of cases here. It happens whenever it's school holiday season and people go traveling and bring back all kinds of bugs.

Mask up and avoid crowded places. 😷

Every day whether you have a cold or not, take plenty of vitamin C (5 grams of pure ascorbic acid mixed in water that you drink throughout the day), vitamin D (125 ug to 250 ug), and a bit of zinc (25 mg) to help the body absorb the vitamins. Also, when not having a cold and the weather permits it, take a 20 to 30-minute walk every day (getting sweaty is not required or very desirable). I started this practice a few years ago and minimized the days of having a cold from basically three months a year to a week or two a year. I have also had Covid twice (non-vaccinated) and got through it without any major problems although really sick for about four days. Without the supplements mentioned (and walking), I am convinced I would be dead by now.

Get well! 👍

Years ago i used to take a lot of supplements when strength training and body building. Did it make a difference ? i honestly couldnt say. These days i hope to get everything i need from good real food, organic when possible, avoiding anything that promotes inflammation, we do need some inflammation but it is extremely easy to be harbouring excess and that is real bad for us causing so bany issues. I also haven't had any injections, have had the so called Covid twice with only mild symptoms.  I believe that is mostly due to genetics and how your immune system reacts, all that starts with gut health. I also believe stress plays a huge roll in our well being, a healthy mind without a doubt contributes towards a healthy body.

That would of course be ideal, but if you know with yourself that you tend to be careless with a nutritious diet, it is better to supplement with nutritional supplements than to abstain. But of course, you should never exaggerate.

Yes you really do have to be on top of a good balanced diet and that can take a fair amount of effort finding out what your needs are. Its a science thats constantly changing with new research, 40 years ago fat was the all evil for the last 10 years carbs have been the bad guys. Some truth in both views but its much more complicated than that and everyone reacts differently to food types. Being sensible is about the best we can do,by cutting out or at the very least reducing processed food in particular sugar and that isn't easy, its absolutely everywhere. Fasting has been a big thing for me this past couple of years, autophagy which has been strongly suggested helps to reset the body through a detoxifying process.

    • @dibs1 Hopefully you see this and post an update. @Knebo Would you happen to know what is the end-shake tolerance for a cal 15xx rotor or is there such a metric? Also, is there a specified height of the rotor?   I got the watch serviced which addressed the rotor grinding against the base plate and case back (i have checked by moving the watch in a circular motion to spin the rotor and have tested it dial up and down) however whenever the watch is shaken lightly the rotor touches the caseback and makes a ding. What is unusual is that is only happens when the rotor is resting at the 9'o clock position. The axle was replaced and reading around it seems that  spring clip, jewel and axel are the three parts that individually or together are causing this issue.
    • Yes, barrel size.  A 11mm spring will push out into a 11mm barrel, no need to go 0.5mm smaller. 
    • Hello All, I’m looking for advice about how to interpret the mainspring specs described in the GR documents and in the catalogues of online sellers such as cousins.  My problem relates to interpreting the value describing barrel size - I’m unsure what the last number REALLY refers to.   For example: 1.10x.0105x360x11  (This refers to GR2628-X) Does the “ 11 “ here refer to the barrel inside diameter of the calibre OR to the diameter of the wound mainspring before insertion? For example if my measured barrel inside diameter to 11mm, I would normally select a wound spring size a little smaller, say 10.5, wouldn’t I?  Or, does the barrel diameter described in the catalogue specifications take that into account and I would therefore order a catalogue size 11 for an 11mm barrel ID? Hope this makes sense. I can’t find clarification of this anywhere. Many thanks for any enlightenment. Cheers, John
    • Let's say, like in a watch, you have  a 70 tooth 4th wheel, which needs to make a turn in one minute, with an 18,000 beat escapement. 15 tooth escape wheel as usual, and a 7 tooth pinion on it.   70 x 15 x 2 /  = 300  That's 300 beats, and there are 5 beats per second, so divide and you get 60s, one minute- all is well. If we do 70 x 15 x 2 / 8 that equals 262.5. With an 18K balance, which will let the escape wheel move one turn in 6 seconds, the 4th wheel will have made like 1.14 turns. So the time display is running fast. But this comes to like 7.5 seconds over per minute, which is about double your gain (maybe I'm wrong- I'm mathing on my phone while writing on my phone 😄) but pretty sure the gain is more than you are observing.   A possible culprit is that crown/4th wheel isn't running true, and a tooth is slipping past a pinion leaf once per revolution. I've seen this. If the platform is original and it's a nice piece they are often pinned, so the depthing isn't an issue. If the platform isn't pinned, check the depthing. And at any rate check the crown wheel between centeres and make sure the teeth are running true.
    • Fast responses - thank you. Yes, I mentioned the 18000bph to illustrate that it's not a matter of touching coils, over banking, shortened hairspring etc. I even took off the platform and temporarily fitted a another NOS one also with 8 leaves and beating 18000 but the colossal gain is the same. I'm resigned to buying and fitting a new Gorge platform plus a 7 leaf pinion escape wheel but only if I think it will work; otherwise it's a waste of £200 and a couple of hours work. Hence the underlying question is: all other things being equal, what would the timekeeping effect be? Is it a simple 7/8ths as fast? Logic tells me it is but can it be that linear?
