Sir, with all due respect your post is very distasteful and desperate to say the least. Going into someone's post about their choice on their watch makes you sound like a joke. How are your materials superior can you go into details? Nasa and F1 have nothing to do with horology. You are speaking of a company (Rubber B) that created the very first fitted rubber strap for Rolex, now they do AP, Panerai, Roger Dubuis etc. I recommend to you reading up some history before making the kind of idiotic statements that you are making. They manufacture in Switzerland along side the top oem brands in Swiss horology. You are saying that your product is superior to those brands also? You should let your customers, sales and time do the talking. I do not own or know much about Everest I cannot speak of them but I can assure you that your product as nice as you might think it is does not share the quality of RB.
