Is the Omega Speedmaster 38705031 legitimate to have a 1450022 caseback? http://www.ebay.de/itm/Omega-Speedm...000266?hash=item3ae836ac0a:g:ZKMAAOSwXetZQoxhPurchases made through these links may earn this site a commission from the eBay Partner Network Caliber 1861 Was it born with this caseback? I thought these models would come with a glas-floor.
I think you are mistaken. The 3870.50 is the same as the 3570.50 but came on a strap instead of the bracelet. The 1861 has the plastic brake and didnt come with clear case back
