thor447 Posted August 20, 2023 Posted August 20, 2023 (edited) 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. Edited August 20, 2023 by thor447 2 1 3 Quote

thor447 Posted August 20, 2023 Author Posted August 20, 2023 It happens to us all at one point or another. I suppose that I am glad that it only cost me a mainspring, and not something more difficult or expensive to replace. Quote
Razz Posted August 20, 2023 Posted August 20, 2023 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.

Waggy Posted August 20, 2023 Posted August 20, 2023 (edited) 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. Edited August 20, 2023 by Waggy Fixed many typos Quote
dadistic Posted August 20, 2023 Posted August 20, 2023 Thanks for this post, I'd post some anecdotes but I'm too embarrassed to admit to all of the times I've shot myself in the foot Quote

KarlvonKoln Posted August 21, 2023 Posted August 21, 2023 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. 1 Quote

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. 2 Quote
LittleWatchShop Posted August 21, 2023 Posted August 21, 2023 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. 2 Quote
TKM3RD Posted August 22, 2023 Posted August 22, 2023 Good reminder. I need to hang a sign above my bench saying "Yo, doofus, slow down and pay attention!" 2 Quote

Print up enough of those signs for us, and you could make a tidy sum from it. Times come when we all need it. 1 Quote
thor447 Posted August 25, 2023 Author Posted August 25, 2023 Despite my inadvertent attempts at self-sabotage, I managed to complete this project. Count me in for one of those signs! 4 Quote
RichardHarris123 Posted August 25, 2023 Posted August 25, 2023 I like the idea of the sign but can't ever see myself saying "yo, doofus" Quote
