Hope more watch brands will bring back date window cyclops - don’t really see this being offered by modern watches, apart from Rolex ofc 

If you speak to watch designers, one of the reasons why they don't want to do the cyclops anymore is because it forces them to use a flat crystal.  Let me explain...  Cyclops lenses are glued onto the crystal.  The clue is perfectly done, cured, and there can be no bubbles nor residues.  The lens is not milled as a part of the crystal (this would take too much time and increase costs).  The costs of this gluing the cyclops lens on increases significantly when designers choose to use curved crystals as the failure rate increases significantly.  And relatively few designers want to be limited to using a flat crystal to design the watch.  Also, brands that employ this cyclops will be wanting to implement it across many of the brand's product lines.  How can they justify one model having it when another one doesn't - it basically says we  think Pilots line doesn't need it when we think divers do need it.  So designers need to think about it cohesively from a brand identity perspective.  

Never thought of this from the perspective of designers.
