I need your personal and practical experience...if you have this movement watch with you

This has a modified (by Hamilton) Valjiox 7753 which is from the same family. It is a pretty beefy watch that keeps excellent time and has around 50 hours power reserve. As @TekindusT said, Calber Corner is also an excellent resource 👍

Thank u very much...and thanks for sharing your Hamilton snap👍

You are going to hear from more erudite members about the Valjoux 7751 movement but it is a modified version of the legendary 7750 used in just about every Chronograph marketed. The 7751 is/was used for multi complications including a Moonphase indicator. I own a Breitling Navitimer 1461 which is a 4 year annual calendar Moonphase which is I suspect a modified 7751, which keeps very accurate time( after a full service in Switzerland) but power reserve is low by modern day standards. Years ago I owned a Baume & Mercier calendar/Moonphase watch that was fitted with the 7751 but the power reserve was inadequate to keep the various functions timely and was returned to the seller at a loss of some dollars. I feel if you are researching some contemporary watch that is fitted with an updated 7751 the power reserve may have been improved. My personal experience with the B&M with the 7751 was positive and may have benefitted with a watchwinder which I do not favour. Good luck hope my limited experience offers some insights into your own investigation

Had a 7750 in this speedmaster date and it went without a service for almost 20 years and was still more accurate than the pro. It was about two seconds slow a day after all that time.

The most important chronograph movement ever made also one of the best watch movements eve made. It has only one problem, it is a chunky boy, that is it

It has a fancy name.

Thank you...your valuable advice is appreciated.

Here is mine, some have a moon phase complication and some don't. All usually have a full calendar with pointer date and 12 hour chronograph. A sturdy and reliable movement it is similar to all other 77xx movements. I highly recommend it, all of my 77xx movement watches has given stellar service.

Thanks John...Nice to see your Breitling
