A few years back, the collective wisdom turned against third-party movements. Despite the fact that movements had always been supplied by specialist third parties (Valjoux, Lemania, ETA), the marketing push from the brands that did have in-house movements began to work: simplistically, In-house was good and third-party was cheap. You often heard the refrain that "at that price I expect an in-house movement". I sense that the feeling has died down on this one. When Rolex (Tudor) released the Black Bay Chronograph with a Breitling movement..not a sound. All the noise around the Heuer-01 has gone...surely that can't just be because TAG Heuer changed the name? So, now there is a new "in-house movement"..the humble bezel. Since we saw the first ceramic bezels a few years ago, there seems to now be a view that aluminium is cheap. I'm not so sure. I like ceramic bezels, but they do give a very different "glassy" looks compared to aluminium. You can get ceramic bezels on lower priced Aquaracers, yet the JLC Deep Sea range all have aluminium bezels at +$10k. I think the choice is more than cost- aluminium is more vintage and in some cases I prefer the look...although no question that ceramic is harder and will wear better. So, is it as simple as aluminium = cheap; ceramic = premium?
