MMMD
·...they seemed to have a lot of them in for service because people thought that they were much more water-resistant than they really were.
This belief might have been instilled by Movado's marketing (the Astronic was called a "Chronodiver" in this brochure from around 1974):
There is also "SUPER SUB SEA" on the back, which sounds pretty darned impermeable.
"SUPER SUB SEA" is followed by "10 ATM" on the back of the earlier Chronodiver seen in the brochure above at right, implying 100m of water resistance.
I had always heard that there were only 100 or so of the first series but given the number I have seen for sale (not a lot but some) I thought 100 seemed a bit hard to believe.
Fully agree... there's no way the Astronic was produced in such limited numbers. I would believe 2500, maybe, but never 100. I see many more Astronics for sale than, for example, Zenith A781's (the red-dialed El Primero in the same case and bracelet as the Astronic), with a production number of 1000, according to Rössler. I'll bet 100 was the production number for solid gold Astronics (see brochure page above).
