Horological Humility: I Had To Re-Learn A Lesson Tonight


Recommended Posts

Around 6 months ago, I acquired my initial set of mainspring winders. Before that, I had been manually installing mainsprings, a task I had grown quite comfortable with. I underwent the usual learning curve associated with adopting a winder, specifically the Bergeon arbor/drum type. While I faced challenges at the outset, I managed to achieve significant success following a few initial setbacks.

However, tonight marked an instance where my confidence with the winder led me astray. As I commenced assembling my next project, I allowed overconfidence to cloud my judgment. I successfully wound the mainspring up to the bridal point, and with a hasty adjustment by hand, I attempted to insert the bridal in the drum and finish winding the mainspring. Unfortunately, my approach was far too forceful, and the bridal was not properly aligned within the drum. The consequence was immediate: a resounding SNAP!  The mainspring broke precisely at the bridal junction.

This mishap was unequivocally my own doing, serving as a stark reminder that the pace of our work, especially when dealing with vintage watches, must be deliberate and measured. Regrettably, I had failed to give due attention to my actions, and the repercussions were evident. This incident underscored the value of patience and attentiveness when working on horological projects.

I couldn't escape the irony that my error led to a $32 order from Jules Borel tonight. Though it had been some time since I last required a replacement part due to my own blunder, this served as an insightful lesson I won't soon forget.

I almost did the same thing 2 days ago. My root cause was I was trying to use a 1 size too small winder for the spring/barrel. It was an automatic as well. I think the winder has to be close to the same barrel diameter and so the bridal of the spring will more easily fit into the winder barrel without forcing the arbor during winding or having the bridal outside the slot.

Is it a Seiko spring? I always hand wind them, that backwards bridal set up doesn't seem to work too well with mainspring winders. I even reached out to Mike on My Retro Watches, who confirmed the same and said he too also hand wound Seiko springs.

It was a Hamilton spring.

Ah yes, I know that *snap* when I hear it.  Heard it at least twice, possibly three times.  I think the time that we really start getting good at using watch winders (and other tools) is when we get to the point of realizing we will never *believe* we are that good, so we go even slower and more carefully that we used to.  It hurts to have to pay out of pocket for parts that I, myself, broke (or lost, like click springs) so some tools I become very mindful of, very cautious with, and may always be on "high-alert" when using.  Perhaps that is the way it should be.  I think that is how we learn sometimes.

So true, I had a friend who used to say "sometimes it has to hurt to learn" I have found this to be true on so many occasions, just part of the human condition I suppose.

I replaced a PW manual wind MS the other day.  It did not use a "bridle" in the automatic wind sense, but had the reverse catch welded to the end.  I was winding in my trusty K&D winder and got close to inserting it into the winder at that last stage and it just popped off.

I think it was a bad weld, frankly.  Easy fix.  Annealed the end and bent it back.

Good reminder.

I need to hang a sign above my bench saying "Yo, doofus, slow down and pay attention!"

Print up enough of those signs for us, and you could make a tidy sum from it.  Times come when we all need it.

    • Good morning,   To be honest, I'm not sure I trust my own logic anymore 😅. But here's a picture of my own (failed!) attempt to install a new rotor axle. I punched way to hard and even split the metal of the rotor. My thinking was that, in my case, the axle sits "deeper" in the rotor and hence the rotor would be closer to the movement plates. Vice versa, I was thinking that a very light punch could cause the rotor to sit rather high. But not sure that makes sense because in both cases, the flat part of the axle and the rotor align equally.     Sorry, but is he saying that the outside of the caseback has been polished to such an extent that the inside of the caseback has deformed/sunk??? That sounds crazy to me because those casebacks are thick! Can you see any signs of that on the inside of the caseback? Have you tried screwing in the caseback a litte bit more or less so that the supposedly "sunk" part of the caseback would move from 9 o'clock to e.g. 6/7 or 11/12 o'clock?  If the caseback is truly deformed, maybe it could be punched/pressed back into shape (e.g. with glass/caseback closing press).      I agree with your choice. But yea, Rolex makes it VERY hard for independent watchmakers to do a perfect job because we can't get (original) parts easily.      Your pictures aren't too bad. But still impossible to see if the rotor isn't perfectly flat. You'd have to look at it with your loupe, from the side (like the pictures), and turn the rotor to see if the gaps (with the automatic bridge plates) increase/decrease.     Finally... how is the up/down play of the rotor? To test, take a toothpick/pegwood and press on the small triangular side of the rotor next to the axle (NOT the big side where the weight is. But the opposite side.). Does that lift up the weight-side of the rotor? There can be some play, but it should really be minimal. If there's too much play, a new spring clip is the first thing to do. After that, one could play around with the jewels. This is too much:
    • could start a new sub-brand: Bergeon-Pro Worked for Apple phones! Ah they already beat me to it:  
    • Hello, those RR pocket watches are nice watches, there are still parts around...
    • The hairspring looks to be in good condition from the photographs, it is natural that the balance will perform slightly differently in different orientations. Assuming there is no damage, the difference may be caused by the balance moving relative to the jewels, not the hairspring itself. So too much space between the jewels (endshake) and the difference will be greater, if one jewel is oiled and the other not, then again a lower amplitude in one position than the other....and so on. If the difference is reasonable (like your 13 seconds) the the best thing to do is to make one position slightly fast (+7 seconds, and the other position slow -7 seconds) then this averaging of the error will make for a more accurate watch in use. If the difference was much greater eg 100 seconds, then you would need to troubleshoot the problem. Additionally, you need to let the watch run-in for 24-48 hours after a service to allow the new oils to work their way in to all the jewels and pivots etc before you make a 'real' timegrapher test, otherwise you can get strange results. For example the oil in the top shock setting may be evenly spread, but not (yet) in the bottom setting = high difference.... after 24 hours this oil will probably have sorted itself out and the difference may be much better.
