I normally wear one of two Omegas I have a vintage 1964 Omega Seamaster Gold with leather band that was my grandfathers, or mostly a 1943 Omega Military Black face, Steel case and black leather band. Pisses me off that I have to spend $150 on a service for it every 2 years though. I also have a Timex Ironman I use when working out.
Currently though I've been wearing this watch a lot:
My girlfriend got it for me for Christmas because she said it reminded her of the car and she knows how much I love it.
