Was discussing with a friend recently as he is looking for a dressy watch... discussion got to debate between these two.
Similarities:
- both cal. 215
- both platinum
- both 37mm
- both essentially time only (as travel time can be “hidden” from view)
- both similar pricing
Differences:
- dial on 5196 more interesting finishing and applied Breguet indices are quite special
- 5196 wears larger on the wrist due to thinner bezel and thinner profile
- 5134 comes on deployant buckle while 5196 on pin buckle
Personally I find the choice rather difficult. I suspect the 5196 has a wider following here as it is a more classical Patek in the traditional sense. Perhaps it is the more obvious choice. 5134 is a somewhat forgotten reference that is rarely surfacing publicly. However I find this version with stick indices and superb stealth complication (which is quite useful and easy to operate) quite cool... tough call for me as both can be argued in favor of... would love to know what the forum votes in this little battle...
