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. I have heard that before about lots of orphan watches in Australia 🤔. How far overseas are you going with buying ? There are lots of good sellers here in the UK, shipping is a bit prohibitive though. Main reason for seeing non cased vintages watches would have been the scrapage of the precious metal cases. I think we decide early on what we want from the hobby, whether that is to repair for the fun, enjoyment and sheer challenge of learning something obscure. To collect watches and have that ability to maintain them, to gain financially from re-sale or a mixture of those. Its also important to remain aware of how deep the rabbit hole goes and how much money it takes to continue the descent. -

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... -

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.
