not make sense to own two watches with the same movement. At least that's what I feel, though many would disagree.
And the Patrimony Contemporaine is a beautiful timepiece. The 'regular' version in PG and also the boutique edition with Black Dial are both breathtaking.
Another piece you could consider is the Patrimony Contemporaine automatic with date (At 6 o clock), either in PG, or if you can find it, Black Dial boutique edition. The latter is a rare bird, and these have sapphire caseback. Putting the date at 6 is a nice touch and gives good balance.
