An observation regarding Patek 31-260 PS QL
One of the editors in another forum have pointed out the absence of interior angles in the caliber 31-260 powering the 5236P. The caliber’s bridges are rounded at the edges but the expert points out that the lack of interior angles are indicative of lack of hand-finishing expected of a high price complication from Patek.

Pl remove the post if it violates forum rules. I thought forumners with expertise in judging caliber finishing could give their views and hopefully more hi-res images of the caliber 31-260 can be added to this and discussed. Red arrows point to the highlighted issue wrt the interior angles ( or lack of it).
