Very interesting article. It’s a pleasure to see this kind of work here. It’s a really important discussion
And it is easy for manufacturers to lengthen the pr and it looks great on a spec sheet it as you rightfully point out, it comes with a price.
A minor correction The FP Journe 1304 has an autonomy/ pr of 56 hrs +-2hrs.
Too Short...or too Long? The power reserve conundrum
Power Reserve – the long and short of it…. While many of us have been discussing new models and the technical innovations incorporated into the calibers as well as the matters of finishing and aesthetics, I felt that it may be interesting for us to do a r...
Excellent post, which i'll comment on shortly, but wanted to correct a minor thing if I may....
The base caliber in the Parmigiani Bugatti you have listed varies, but is well over 200 hours in its forms.

Thanks for the correction.
Yes. FPJ has used the parallel barrels to drive accuracy instead of elongating the power reserve in Cal 1304. So the power reserve is kept at 56 hours.
It’s only the Octa automatic movement that has 120hrs of pr
Usually Journe pieces don’t have long pr to preserve isocronism.
Superb article. I will take my time to read through this.
After a great explanation, I'll need to look at all of those movements a lot more closely. Excellent post, especially with the examples given.
Very informative and interesting post. So many options...
In general I would prefer accuracy over length of power reserved, some of your example provide excellent rate even with a super long reserve...
The BP and the Chopard are really nice movements.
Moser is a standout too. Thanks for sharing this, power reserve is among the most important features. I mean you can always have endless watch winders if you want or set a watch each time but I like the process of switching watches to be effortless.
Corrections to the description of power flow
Please see the correction in italics . Apologies for the error. Can moderator either replace the two initial paragraph in my original post or place this post below the original for correct reading. Thanks. Watches need to be fed continuous energy to drive...
