No worries, good sir! Always a pleasure to help out.

As a reference, my Lord Marvel takes approximately 40+turns to reach its full stop. Do let me know if you need more details, have a great one!

Hey there! Thanks for reaching out, I'll do my best to provide some help.

Theoretically, the 5740C movement has an approximate power reserve of around two and a half days. Speaking from personal experience, mine is right around there as well. There is a direct correlation between the around of crown winds and the approximate power reserve. I can't remember the black and white source of this information, but it was on a WatchUseek thread, you may want to search for it.

Therefore, in your good self's case, 12 hours is extremely poor and I would definitely take it for a service. It could be just a lubrication issue but to be sure, do ask your watchmaker for details. Has the watch been serviced before?

As for overwinding, I would like to comment on this myth as well. From my personal experience, there should not be worries on owerwinding, IF, your timepiece is in good condition. (Serviced regularly etc etc). I personally own many vintage pieces (my oldest being from 1908) and I do my best to wind them to their stop. Of course, this takes experience and never go PAST a full stop once you've felt it in the crown.

Looking forward to hearing from you!

Ahh I see! My apologies as well, I wrongly  interpreted your comment. And yes, the pointer date complication is indeed beautiful 😍💪🏽

Thank you for your comment, good sir, unfortunately it is not for sale😄

Thank you for your comment, good sir! And apologies for the late reply, I was off Watchcrunch for a while 😄

Just Googled your model and the piece looks spectacular! Congratulations and I wish you all the best in becoming the guardian of such a timepiece💪🏽

Thank you for your kind words, good sir! Its a relief to hear I have chosen wisely and I will definitely protect this beauty the best I can! I have to thank you personally again, as you have been one of the contributing factors to me being comfortable and somewhat adept at navigating the vintage watch market. If not for your advice on this platform, I would have been bamboozled into buying a Franken from hell itself! I thank you once again, good sir! Always a pleasure to hear from you💪🏽🥳🥳
