For the Patek. As shared in a previous post, you will always have chances to afford new timepieces in the future, but it’s harder to have that special moment of getting a more collectible watch with your own name on it at the Patek dealer. It’s something pretty special, and while I also think highly of the Remontoire and some cash back, I suspect there will be more opportunities in the future to get a Gronefeld customized than to get a steel Patek with your name on it in the foreseeable future. Save up!
Cheers and good luck
