New Speedmaster - Hesalite or Sapphire There are a few main differences between the two. Here's my short list. 1. Height Hesalite - 13.58mm Sapphire - 13.18mm 2. Applied Logo Sapphire is an homage to older (pre-moon) Speedys with the applied Omega logo. Hesalite - Print Logo Sapphire - Applied Logo I can see reasons for not having this on the Hesalite version. Not having the applied logo of the Hesalite gives people a modern speedy and proper copy. 3. Bracelet Polished Links vs Satin Hesalite - Satin Sapphire - Polish This is simply preference in my opinion. 4. Exhibition Caseback Hesalite - Solid Sapphire - Exhibition Of course the main difference is the crystal itself. I did this short list to give others the same info. It's a difficult decision for me as like most of you, I've been looking at these non-stopped for the past 24hrs. 1. The height is a huge + for the Sapphire 2. The applied logo is more attractive to me especially given the price point. 3. I'm leaning toward the Satin but the polish is a nice flashy touch. 4. Solid is always my preference. All of this said, I think for the first time I want the sapphire version. The 1 & 2 are important to me and I also want my watch at that price to have a piece of sapphire. I don't want to polish my new speedy after I scratch my crystal.
