For those of you who have read and were interested in my previous post on Harwood watches (the first automatic watch) here is another interesting example. This one was marketed by Blancpain in Barcelona around 1930. The hand setting is now done by turning the watch back and there is a four-cornered screw head (arrow) that turns against a leaf spring to adjust the pressure of the slipping clutch that prevents over winding.

Nice watch Colin, you certainly know how to get my attention. Does the back just snap off and are you going to service this one?

The back does indeed just snap off as does the font bezel. The movement is front loaded with two half-head screws to hold it in place. This arrangement makes it less dirt proof than the more conventional Harwood.

I have just done a complete service and it is now keeping time to better than one minute per day. The silver dial with gold numbers is original and has just had a light brush over to remove a little dirt.

Harwoods have a reputation of not running for more than 12 hours, but this is nonsense. The power reserve depends on the Schild movement and is well over 24 h. A mal-adjusted automatic winding system probably accounts for poor performance. But this one I have worn 16 hours per day and taken it off for the 8 hours overnight and it has not stopped since I began to wear it on the 1st January.

The Spanish patent number on the winding bridge is a mystery - some have attributed it to the back-setting feature, but it cannot now be found in any Spanish official record. It is thought that perhaps, although filed, it was never granted. The novel slipping clutch screw adjustment permits easy and stable over-wind protection. I wonder if this was a Blancpain add-on?

Interesting Colin, I thought the screw was to adjust a slipping clutch. I do like these Harwoods, I was wearing mine over the Christmas period, although I have still to service it.

      A lathe with indexing that won't break the bank?

      By JohnR725 · Posted

      interesting video nice to see the machine what it can do now I wonder what it costs and I'm sure it's not in my budget. Plus the video brought up questions but the website below answers the questions? What was bothering me was the size of his machine 4 mm because I thought it was bigger than that? But then it occurred to me that maybe they had variations it looks like four, seven and 10. With the seven and 10 being the best because way more tool positions in way more rotating tools. Although I bet you all the rotating tools are probably separate cost https://www.tornos.com/en/content/swissnano   Then as we been talking about Sherline. Just so that everyone's aware of this they have another division their industrial division where you can buy bits and pieces. I have a link below that shows that just in case you don't want to have the entire machine you just need bits and pieces. https://www.sherline.com/product-category/industrial-products-division/   Let's see what we can do with the concept I explained up above and bits and pieces. For one thing you can make a really tiny gear very tiny like perhaps you're going to make a watch. Then another version the center part is not separate it is all machined from one piece. Then fills gear cutting machines have gone through multiple of evolutions. A lot of it based on what he wanted to make like he was going to make a watch unfortunately eyesight issues have prevented that. Another reason why you should start projects like this much sooner when your eyesight is really good or perhaps start on watches first and then move the clocks then local we have from the industrial division? Looks like two separate motors and heads. Then it's hard to see but this entire thing is built on top of a much larger milling machine as a larger milling machine gave a very solid platform to build everything.   Then like everything else that had multiple generations are versions the indexing went through of course variations like above is one version and the one below was the last version. Now the version below I mentioned that previously and somewhere in the beginning to discussion and somebody else had one in their picture. As it is a really nice precision indexing. Then I wasn't sure if I had a the watch photos here is his unfinished watch. No he wasn't going to make a simple watch like none of his clocks were simply either what would be the challenge and that.

      Lab Coats

      Use a Portwest Howie lab coat. They are the biological type so they have tapped cuffs so you don't end up getting the loose cuffs of normal lab coats catching everything.

      Chinese tools debate

      By Titanium · Posted

      Some of the Chinese tools ae great and can be purchased at a fraction of the price of Swiss ones, some are complete garbage and some I'm convinced are coming out the same factory as the branded ones.

      I found this string about this problem. I've not gone through it all, but I believe it also mentions making a spring. If not in this string, the info is online.
