    The text in this reminds me of the Rockwell joke video.

      I've not seen this before but thanks! Where do I give them all my money to finally confobulate without worries for side fumbling?

    The use of silicon for the escape wheels cannot be stressed enough. Both the lever and escape wheel in Rolex's Chronergy system are made of nickel phosphorus alloy — the same material used by Omega in the escape wheel and pallet fork of the co-axial. With the Dynapulse escapement, the Crown has opted for silicon throughout, in both the escape wheels as well as the mobile blocking element. Rolex's silicon material is inherently self-lubricating, anti-magnetic, temperature resistant, hard, light, and quite resistant to shock.

    Includes some cool animations even if you have no time to read the full article. Provides some history of alternative escapement mechanism arrangements and usage of silicone, and then the Rolex Dynapulse.

    lay person opinions

    From a maintenance perspective the whole escapement system has always been a giant, finicky pain in the behind. Going with this easily reproducible system that's far more resilient will be a game changer for even at home tinkerers to be able to service their own mechanical pieces.

    Surely other watchmakers will follow suit with more advancements using new materials immediately. Looking forward to Omega's and Seiko's response / unveil of concurrently developed tech in particular.

      Note that the article consistently refers to the material in use as silicon, an elemental crystalline solid, not silicone, a class of silicon-containing polymer oils and plastics.

      (Both are conceivable inside a mechanical watch, but the use of a plastic material for the actual mechanical components would be… unorthodox, at least.)

        Unless you're Seiko. Their most used movements use a few parts made of plastic I belive.

          I think compared to Rolex one could comfortably call Seiko "unorthodox"…? ;) But thank you for the correction.
