New Video Uploaded. A Primer On Regulating A Watch.


Recommended Posts

A much awaited video Mark, I am eagerly looking forward to the follow-ups.  You asked for feedback as to topics for inclusion in future videos on regulating watches.

I am particularly interested in what position should be the start position for regulating a normal wristwatch worn on the left wrist,and what is the next sequence of positions.

My chrissie present was a timegrapher and I now see that some of my watches that ran perfectly (!) may not be doing so after all !! 

I would also like to know how amplitude factors in and what is good/bad/acceptable. 

The effects of good/bad lubrication of the pallets would also be helpful.

You may well have planned these into the future videos, if so great news.

Thanks

I haven't used Keynote for several years now so I haven't kept up to date with new features, but it has always been a very nice app. It's really blows Powerpoint out of the water.

 

As an alternative I would recommend Apple Motion, which is a bargain at $50. It has nifty things like linked behaviours which would be handy for movement simulations like the one you did in this video.

 

 

Had a really good look at Motion and it is really an amazing piece of software Rob, thanks.

I think this will really help with illustrations going forward.

Yes it's pretty nifty, isn't it? Granted, not as easy as Keynote but way more powerful.

 

It enables many more advanced effects. You could do green screen recordings with that piece of unmounted laminate seen in the background of the latest videos for example. ;)

Indeed. I got a wheel spinning within a few minutes. Simples!

Hi Mark. So do I take it a quality watch a holy trinity or a Rolex would automatically be a guaranteed dead single beat line, and if so how long would it be before that reading starts to decay whether gaining or losing. Is it true that the more expensive the watch the straighter that line will be or are all watches true at first.

Many expensive watches will be measured to a certain standard, the COSC Chronometer Standard for example, which would guarantee a certain level of accuracy when the watch is brand new. The fact is that measuring a watches rate on a timing machine will give you a sort of lab test reading for that moment only, not a real world test. Other things affect timekeeping such as temperature and position. But those readings are a very good guide and with a consistent accurate reading on the machine, one would expect real world usage to reflect that.

    • Thats a good record Michael,  i always do a quick scan through sone of the  feedback comments to make sure there are a good few of them relating to sales and not just purchaese.  Feedback can be faked but you can usually spot the dodgy sellers.
    • No, trus me, this is totally wrong. Firs of all, there is theoretical lenght for a fixed other parameters (spring thickness, barrel internal diameter and arbour diameter), which will give maximal power reserve. This is written in all text books, but I have never seen in  the text books mathematical expression (formula) of the relation lenght/power reserve. I am to lazy to generate that expression now, but will draw for You the graphical representation of it. As You can see, there is a maximum in the middle, but the slope near the maximum is really small, so even change of the lenght of let say +/- 30% doesn't lead to significant change of the power reserve. More to that, sometimes movement designers put much longer springs in the barrels than the theoretical lenght for maximm reserve.  This is ecpecially in high grade movements. You will sometimes see that the spring covers not the half, but actually 2/3 of the barrel free space. The designers compensate this loss of power reserve by usage of bigger barrels. This way they achieve much smaller difference in full wind / end of power reserve torque. In such case, reducing the spring lenght leads to increasing of power reserve...
    • Hi you can get parts/ tech sheets from cousins uk on therir down lost page, also print rest has some scattered about, cas ker, Esslingers, my retro watches, watch guy there is a few to trawl
    • I only buy mechanical personally, as it's all that interests me. There are a few electronic movements I find interesting, but they're not the sort I tend to see very often at all, and wouldn't come up in any of my searches. I have been given a few quartz watches over the years, but they all just sit in a bag in a drawer. Once I hit some critical mass, I'll hopefully get enough motivation to either sell or donate them.
