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 !
