I had the Tissot Le Locle, and it doesn't have applied indices, it has an embossed dial where the raised parts are painted. The numerals were the part I disliked the most about the watch, it just never looked right to me. Serif roman numerals should always be printed, they look unbalanced when realized using applied indices.
On my Patek Philippe Calatrava 5119, the hobnail bezel is already a very visually engaging design element, and applied indices would have overpowered the watch.
Sometimes, less is more when it comes to design.
