I am interested in picking up a Speedmaster reduced. I have found countless articles describing the differences between the reduced and the professional but not much on the differences between the reduced models themselves. Any subject matter experts who can describe the meaningful differences between reduced models? Also, how might an amateur collector tell one reduced model from another?

    For the ones that resemble the Moonwatch, there are two references

    1. 3510.50.00. This is the first version. Hesalite crystal, 5-minute Arabic numerals at the indices.
    2. 3539.50.50. This is the “second generation,” was only made for a few years. Sapphire crystal. No Arabic numerals. Slightly upgraded clasp on the bracelet. Improved water resistance.

    So the main choice points are

    Hesalte vs sapphire?

    Arabic numerals or not?
