Subtleties in pulling out a Speedmaster crown...

You got me! I give up. Mercy -- Tapping out.
Your sharp intelligence sees right through my motives. It must be because I want to sell something... Genius

Well that's one option...could also be that your mom grounded you and you are stuck in the basement.

I call it "parts needed"...

I managed to save the rusty sliding pinion, but the winding pinion was too far gone. It's a discontinued part on a Cal. 321 (which this is) and going to the well of the open market is not an inexpensive experience. The setting lever is still stocked for the 321, so although it was replaced it wasn't expensive (at least relative to the winding pinion).

I would have thought that with the cal 321 now being resurrected, the discontinued parts would now be re-continued. Or am I being naive about something? (Of course, the work you are describing could pre-date the 321 re-introduction.)

No, this watch is in my shop right now, so this is a current service. Despite the many promises and assurances made that 321 parts would be made available again, they have not been.

I've been skeptical of the promises from the beginning, and again I hope I'm wrong, but despite the fact that the case, dial, hands have been made available for the "new" 321 model, none of the movement parts are.

I liked your first reasoning much more. Resorting to Momma put-downs - was fun in Jr. High.

Sorry to bring up memories of last week for you...😉

Since I went to public school in NJ, I’m very familiar with Yo Momma put-downs. And to be technical about it (since were on a watch forum), he didn’t put yo momma down: but he did bust all over you...

And to be technical with you: probably unlikely given time of year. Or are you suggesting summer school?

Well, you know the kind of kids that had to do summer school, right? 😀

Awww buddy-buddy? What is this tag-team? Summer is here.
Maybe get together (once your fingernails grow back) and we can have a Summer School practical exam on how to pull the crown out.
It’ll be a Joy of fun I guarantee it.

Not even close; Al has kicked my ass so many times it would make your head spin. It’s all in good fun though, you get challenged, you get an ass whuppin’, but, in the end, you learned something. Like what prevents a stem from coming out...or how to correctly execute a Yo Momma break.

Yes indeed very educational. Besides the “Yo Momma” bit, the lesson on how to pull out the crown from a Speedmaster was especially entertaining.

Glad you’re being amused. That’s what we live for around here.

Somehow I doubt that he'll get anywhere near.

I see he's already been knocked back once...

And just marvel that this whole thing started by someone asking how to pull out the crown on a watch. Simple question for OF members you say? I think not.

I nearly forgot about the very first question ^^

So, forefinger nail under the crown, thumb on top of it to apply a counter force... I used only the nail before (no thumb) and changed my habit when the OB found it hard to pull out the crown and immedialty asked me if I was using 1 or 2 fingers. Apparently the 1-finger method could bend the stem...

Talking about pulling out the crown, I have 3 manual watchs and all share the same "feature": as soon as I wind the watch, I cannot pull the crown out anymore. I have to slightly "unwind" (technically it does not unwind anything but you get the point) to unlock it.
And no, they are not supposed to be screw down crowns 😁

Anyone also experienced this and any idea of what could be the cause? (V92, 930, and GP12.3 in case it matters)
I am guessing that the torque applied when winding creates a kind of lock between the winding pinion and the sliding pinion but I do not understand why exactly... (the 930 is in deep need of service and even more - but the 2 others were taken care of recently - at least supposed to be)

Bend it, or perhaps at least cause some abrasion and eventual loss of material from the angulated pulling. A lot of one-finger crown pullers though. Thanks for responding.

I have this exact same issue and have been meaning to post about it. Happens with my Baltic Bi-Compax and a couple caliber 601 models I have.

This is a very informative thread, mostly due to Al’s photos and explanations. An additional question, though: is this contact area between the set lever post and the slot in the stem typically lubricated?

On watches that I service it is. I use a very very thin film of Mobius 9504 applied to the groove in the stem.
