: Why is this the cheapest speedmaster? Isn't more jewels
: better? Isn't this the first moonwatch?

This is the "Moon-like" Speedmaster automatic It is smaller than the Speedmaster professional "Moon Watch" The perpetual secons and chronometer minutes are inversed

The 3510.50 based on omega caliber 1140 power reserve of 42h, 45 jew. 28.800 alternaces per hour. Mouvement based on ETA 2890 and a chronometer module (you can see than the crown and the buttons for the chronometer are not in the same plane. 30m water resistant, choc protected an anti-magnetic balance. Nice mecanic, i have one and it works -1 s/day.

The 3570.50 is the historical Moon watch, based on a Lemania mouvment 21600 A/h, MANUAL Winding. 30 m water resistant, choc protected, magnetic protection (including inner carter or soft iron). It is a "real" chronometer and not a modular one. It is the one that passed all the NASA tests. I have one scince one month it works fine +5 s/day.

Ther are also Speedmasters automatics based on Valjoux mecanismes, non modular chronometers sub dials at 6, 9 and 12. Examples: Schumacher Speedmaster. All 28.800 A/h.

Ther is a lot of information about this watches is the forums around. You can also read information in the Speedmaster Professional Club (OSPOG see link in this web site). All the Speedmaster are nice and well donne, chose the one you like.

The automatic 3510.50 is nice one, i initially chosed insted of the professional because it was an automatic,less crown moving because automatic so better water resistance durability, more A/h (supposed better for accurancy), smaller size, less expensive, similar nice desing...

The problem was that...it was not THE Moon one. Finally i get the professional one, but i whil use the auto when going around water.

Best regards
