Just purchased another Omega Speedmaster Professional moon watch, this one is about
twenty years old,.The first owned by my Dad is to valuable as it is seventies 321 movement, never used it.But this one i will be using , although cost $2000 to
$8000 depending on condition ,year, specs.Fabulous they are 48 hour mechanical wind
,42mm dia,has the unbreakable 861 or 1861 movement,and have the famous Tachymetre, so you can time your Porsche 911 quarter mile .Very interesting when
they tested all the makes back on the man on the moon,Omega was the only watch to
pass all tests,the same manual wind you can still buy today. These a bit like our older 911s going up in value every year. My latest gains 1 second a day. My advise if you buy one spend from $2500 to $3000, you will never loose your money.
