Here is a refreshing change a discontinued Omega Speed-master reduced ref: 3519.50.00 automatic based on the original version on the Moon watch but slightly smaller. This model unlike the original version is automatic as people genuinely prefer as no need to wind every 2 days, both still have hesalite plexi glass and chronograph movement,this is 39mm in size thou. A cheaper alternative to the moon watch plus with added of a automatic movement.
