Difference between the Patek Philippe 5107 vs 5127

[perpetualman88]

All I know is that the bezel on the 5107 is a bit thicker than the bezel on 5127. Other that that are there any differences between the two models? Movement? lug sizes? ect?

I'm not super-familiar with these models, but I did a little research.

The 5127 has the 324 calibre, while the 5107 has the 315 calibre. 29 jewels in the 324 calibre, 30 jewels in the 315. Look very similar though, probably just the next "evolution".

Lugs look very similar between the two models in question. Hands might be slightly larger on the 5127. Bezel is the most obvious case difference, I prefer the thinner 5127.

Thanks so much rosspanics it is much appreciated!

I know the 5127 is the evolution of the 5107. I wonder want kind of differences there are between the two different calibre movements.
