Member X 91 Posted June 15, 2010 Well, another n00b question from me... Why do Rolex use all the different shape crystals they do? For example, Subs and Milgausses and DJs/DDs (and most of the modern range bar the DSSD) seem to have a flat crystal, whereas the older models all seem to have protruding crystals in a top hat shape or a large domed shape. Is it just the case that the older crystals aren't as strong under pressure as the new crystals, so needed the extra depth the weird shapes bring, to make them stronger under water or under impact? (Like the DSSD?) Or is it just an aesthetics thing?? Share this post Link to post Share on other sites
trailboss99 996 Posted June 15, 2010 The older crystals are perspex mate. They need to be thicker thus the height difference. Col. Share this post Link to post Share on other sites
fakemaster 0 Posted June 15, 2010 Technology has changed. If they could have made them flatter they would have Share this post Link to post Share on other sites
RolexAddict 1 Posted June 16, 2010 a domed plexi is more resistant to shocks and water weight than a flat one, if flat, like on the 1680, it is positionned higher and the flat surface is thicker. Just mechanic contraints and physic considerations. Also domed design help to catch light and avoid deformations effects when reading the dial in deep water. On another way, the green insert on the LV has an incredible luminosity under water, more than the classic black. Share this post Link to post Share on other sites
Member X 91 Posted June 16, 2010 Cool, much as I thought - I guess a dome distributes water pressure more evenly! I think they look good, either way Share this post Link to post Share on other sites
