    Well, I am glad to be here as a fellow owner; it took me a while to pull the
    trigger on my Ingenieur Chronograph Silberpfeil NOS (1 of 1000)

    It's on its way now and will deliver this coming week together with a NOS
    stainless steel bracelet for a "full set"

    The IWC-manufactured 89361 Calibre probably lay dormant for most of its life
    since it left Schaffhausen (2013-14 ?)

    How do I determine the actual year of manufacture and go about maintaining
    this watch

    Do I treat it as new, wear it and servikce it 4-5 years from now so long as it
    keeps accurate time (what should I expect +/-) or is time elapsed already from
    the date of manufacture the determining factor

    Thank you all !
