I guess you can call this Obscure to me that means under the radar stuff and sort of unknown not the stuff every buddy else has. I been collecting vintage watches for over 20 years or more and I did not learn about these until this year when I saw a Wyler life guard for sell on a forum sells section thought it looked like a rolex explorer. I passed but it made me search out Wylers vintage divers and I picked this one up off eBay just back from getting it service were I had the crystal replaced they are well built. And a bang for the buck. I thought the bezel ring mite of been glued on but my watchmaker got it unstuck so now the bezel ring works perfect.
