I recently snagged a Snoopy watch. It was listed as not running, and it's missing a crown. It turns out to be a Timex "BN2" movement (I think). Google thinks I have fat fingers, and that it's not a thing; and maybe it's not... I don't know. I figure the Timex guys would know though.

Anyway, it turns out, the watch is in phenomenal shape. The crown must have come off early in its life, and it spent the last 60+ years in a drawer. The plating is excellent, the movement looks brand new and runs well (I haven't timed it yet). Other than a small crack in the crystal, this could easily be a very nice watch (for a Snoopy watch). 

Here's the hangup though, the stem isn't threaded, it's splined. The crown seems to need to be pressed on (?). I've not seen that before. Is this a Timex thing? Where does one find such crowns? Are the crown/stem supposed to be an assembly? Please advise.

Hi   Looking at the back plate it looks like a 24, Have attached the 24 manual and a couple of others for you.

I note there are no numbers on the dial so the will most likely be on the back, from the number you can devine its modle and mfg date.

I'm going to have to say it's probably not a 24 (assuming that's short for M24). Between the images at Ranfft and 17jewels, it's all wrong.

Ranfft suggests either M102 or M78... I'm leaning in the M78 direction given the lack of production numbers, but even then that movement is stated as being from 1965-on.

That's all fine and good, but the question is about the splined stem/crown. Cousins does not seem to have that as an option (as an example), or at least not using terminology I'm familiar with.

The M78 manual lists the crown/stem as an assembly (M102 makes no mention of it at all). That makes sense from what I am seeing; I've never seen a splined crown/stem. The number it shows is 401/1, but that seems to be a pretty generic part number, and I don't know how that would account for length unless they all went into the same size case.

OK. Found some time. I pulled the movement out, and under the reflector ring there is more dial. 

"UK 81713 11483" a 1983 114 movement. Ranfft doesn't have that in their archive, but it's on 17jewels. Following the crumb trail, it reads like the M114 is an M104, but produced in the Phillipines. It looks like that number is not in any of the above documents...

As I dig around on eBay for stems, I see they all have the crowns pre-attached... back to the assembly problem.

 I would think finding a NOS replacement crown and stem would be next to impossible. I can only think of one person who might have some.

If you have a lathe, making one is relatively straightforward. As you already have the original stem, rounding off the square section of the stem ( or the spline as you call it ) and the cutting threads for a commonly available crown. You might have to change the case tube as well as Timex uses a really fat tube.

I do not have a lathe... There are a ton of NOS crown/stems on eBay, and I'm not in a rush. I just need to be able to figure out what it is I'm looking for. Now I realize I'm not going to find just a crown and reattach it like I initially thought.

      Venus 178 hour counter creep

      By watchfellow · Posted

      Hi everyone, I put together a Venus 178 recently, but found that the hour counter "creeps" ie. runs when the chrono is disengaged. This is the similar type of setup as the Omega 861, where the hour counter is driven off the mainspring barrel, but stopped when the chrono is disengaged by a friction spring.  Am I correct in assuming that the friction spring for the hour counter driving pinion should be dry? I am guessing that the issue will be either the spring or the driving pinion, but while the driving pinion has some wear the spring looks decent.  I've attached a couple of photos in case anyone has any tips. Thanks in advance!

      Setting power reserve on LeCoultre Futurematic

      By watchfellow · Posted

      Thanks everyone for the replies. It seems setting the hand is a bit of a guessing game, and I thought there would be a very specific way to do it. Since the reserve indicator hand moves clockwise as the spring is wound, I tried setting it right at the start of the black side. But setting it there doesn't really make sense, because by the time the spring is halfway wound, the hand is only at the end of the red side... In my head halfway wound shouldn't mean the hand is still "in the red."

      Lovely part of the country! I spend most of my days driving along the A64 for work in and around York. I'll be sure to drop plenty of questions soon! I've actually got a couple of watches on the way that I'm pretty sure I'll need some help with! They look pretty beat up from the pics but I love a challenge and an excuse to buy more tools 🤣

      Help - London Elliott Mantle Clock Night Silence

      By oldhippy · Posted

      I have two of these in my home. You need to remove the movement from the case, take off the hands and remove the dial and take a few good photos of the front plate so I can see what the problem is. The round nut unscrews and the hands pull off pull them off from the center and not the tips as you could break them.
