Horological Meandering - Winding the watch

Winding the watch

Glad you like the watch. The reasons you described are pretty much in sync with my views on it.
As for the winding, it feels quite smooth. I'd say it is comparable to the two manual wind Reversos that I have. It's not as smooth as my Rolex Prince (which is the smoothest winding manual winding watch I have), but smoother than the JLC Master Ultra Thin (whose winding smoothness is just average, maybe suffering a bit from the small crown).
The five indents on the crown make it very easy to grip and wind, and there is a substantial feedback/pushback from the main spring. Not quite sure what causes that, but it might very well be a property of the sperodrive feature. Based on what I can see on the back of the watch, the barrel wheel is not larger that usual, so I'd expect a standard length mainspring. Getting 56h of power reserve out of it should therefore be a result of the minimized friction of the barrel wheel when the main spring unwinds. And it seems that this low friction can be felt while winding the watch.

Eterna Madison: Quite a rare bird

Just received my latest watch today. While it was not a Black Friday purchase, the price was still very attractive. And the watch is quite interesting: An Eterna Madison Sperodrive, a tonneau-shaped time only (hours, minutes and central seconds) manual wi...

Glad to see this one

You don't see much talk of modern Eterna's, but I have to say that this one looks nice, especially the movement layout and design. Are those heat blued screws on the movement? Congratulations on this acquisition and thanks for sharing with us.

Not sure about the bluing process...

The screws might be heat-blued or chemically blued with bluing only thing I can say is that the slots of the screws are blue too, so there was no nickel coating anywhere on the screws at the time of bluing.

Original and interesting. Thanks for the presentation of your watch. [nt]

Finally! I'm thrilled to see a Purist taking the plunge . . .

. . . on one of the few watches that have been on my wish-list for many years other than GS or G O. Why? A manufacturer in the truest sense of the term. A case that's utterly pleasing. Fitting dimensions and proportions. An austere dial of classic design....
