I have just completed level 3 of the Watchfix course and was looking to move on to level 4, which says it will feature movements with automatic winding and calendar complications. This seems to have been in development for 2-3 years and has been showing as 84% complete on the course page for many months. Does anyone know when/if this will become available?

I have various practice projects lined up after working with the st3620 for few months now. Basically I have a "standard" movement with no complications; some with a date complication. and one with auto winding and date. What I'm looking for is some information to get me started which is why I thought the level 4 course was the place to start. But...

Can anyone recommend any resources to start learning about movements with basic complications? I'm not ready for chronographs yet!

Thanks, Bill

Hi @Bill2024

Everyone has a different approach to learning, some read, some take courses or watch videos, some just try it out. 

Personally, I'd just take one of your less expensive projects - maybe with just one of the two complications. And give it a go. 

That is if you feel comfortable with the basic manual wind movements. Especially date complications are often not so difficult (especially when they're without a quick-set). 

Post your project/calibre and ask your questions in a new thread. I'm sure you'll get all the info you need.

 

 

PS: there was some uproar recently in another thread about Mark's absence and not reacting to messages. Probably don't expect that course to come out anytime soon.

Thanks @Knebo, that’s good advice.

My current project (first actually) is a basic mechanical wind with no date complication but with a centre seconds hand - different to the ST3620 but similar enough for me to work on. I’ve disassembled / assembled it a couple of times and am waiting for my cleaning supplies to arrive.

My next project will then be an old cheap Rotary with a date but no quick set functionality.

I like to have some idea what I’m doing before jumping in to working on anything so I’ll look around for resources on date complications on movements.  

It’s a pity about the level 4 course but, like you say, I had a feeling that it was not coming any time soon.

which calibre? have you lloked for any YT videos or walk-throughs on WRT for that calibre?

While there are always similarities between date complications, they can also be quite different.

The movement is an AS 1901 with non-quick set date and centre seconds

It runs but the hands will not keep time, although they can be set with the crown in the first position. The hands move extremely easily when using the crown.

My limited diagnostic skills tell me this might be a loose cannon pinion? It was cheap because it was advertised as a non-runner .

Yes, sounds very much like a loose cannon pinion! Relatively easy to fix (or to replace).

You may not have seen it, but he base calibre (without date) has a full service video in several parts by Mark:

 

After that, it's useful to look at Ranfft's page. You'll find out that there are many related calibres that share the same movement architecture (just with different beat rates and complications -- i.e. with our without automatic, with day, day-date etc):

https://ranfft.org/caliber/877-AS-1901

When you start looking for these other calibres on YT, you find quite a few! 

here are a few examples I found for you. The date complication should be the same as yours -- even if they also add a day and/or automatic module.

    • Believe the relume (not a fan) was done a long time after the damage. 
    • I can only think of some chemical reaction to reluming
    • I have a little milling attachment for my WW lathe, but very rarely use it and not for wheel and pinion cutting. For that I use a small Sixis 101 milling machine. I normally do direct dividing, but sometimes have to do an odd count and use the universal index which also fits on the Sixis.   Back in the day when I didn't have a mill, I would cut gearing on my Schaublin 102. It has a universal dividing attachment which fits the back of the spindle. Both it and the one for the Sixis are 60:1 ratio, and with the set of 4  index plates I can do almost any division. When I've had to do a strange high count prime number, I print a disc with the needed division and just place the plunger on the dot. Any position error is reduced by a factor of 60 so still plenty accurate.   The machines are a mess in the pics as I'm in the process of making a batch of barrels for a wristwatch 🙃.   This is the Sixis. The head can also be placed vertically, as can the dividing spindle.   Dividing plates. The smaller ones fit another dividing spindle.   Universal divider for the Sixis. I put it together with parts from an odd Sixis spindle that takes w20 collets, like the Schaublin 102, and a dividing attachment from a Schaublin mill.     The dividing attachment for the 102. The gear fits in place of the handwheel at the back of the headstock.   And the little milling attachment for the WW lathe. I just set it on the slide rest to illustrate the size, you can see from the dust on it it really doesn't get used much. I think only when I change bearing in the head, to kiss the collet head seat (grinding wheel still in the milling attachment).
    • I read a lot about the quality (or lack thereof) of Seiko's 4R, 6R, 8L  movements...or more specifically the lack of regulation from the factory. Especially when compared to similar priced manufactures using SW200's or ETA's. I thought I'd ask those more in the know, do the 4R's and 6R's deserve their bad reputation, is it fairly easy for someone with minimal skills (or better yet a trained watch mechanic) to dial in these movements to a more acceptable performance.    For background I spent more on a 1861 Speedy years ago, expecting that the advertised 0-15s/d  would probably perform more like 5-7s/d. In reality it's been closed to 2-4s/d.
