Good Morning.

I bought a few days ago my first Rep watch. It is a Hublot with an Asian movement 2892. One of the things that caught my attention is the short duration of the power reserve: after wearing it for more than 5 hours on the wrist, I have left it on the table to check the duration of the power reserve. In less than 5 hours the clock has stopped. On the other hand, the Gen watch, as Hublot indicates on its website, has 48 hours of power reserve. Is it normal that in my Rep watch the power reserve is so little?

You'll probably need to give a little more info. Most of my mechanical watches don't run at all when I take them out of the box... ;)

The 2892 movement requires a lot of use and/or rotations of the crown in order to be fully wound. I posted in the other thread two of those watches have 2892 movements with power reserve indicator. it takes me a good 60 to 80 turns of the crown in order for it to be fully wound. This is due to the gear ratio that they chose when the movement was originally designed by ETA. Comparing this to let's say an ETA 7750 movement, which takes maybe 40 turns to be fully wound and run for about 42 to 44 hours. Once they're fully wound both of those watches will run for give or take 46 hours.

Here's the two watches im referencing, both have an ETA 2892 movement with a soprod module for the power reserve indicator.
