Shopping at your lazy chair for a new Omega or more than one new Omega is possible. Shopping for straps and other goodies was earlier possible. Have fun at www.omegawatches.com
If I remember correctly, Omega started online sales in the U.S. in late 2017. I purchased a NATO strap online in May 2018.
You still can only buy NATO straps online, not the regular leather or Nylon straps. And I detest NATO straps.
