Circa 1960s.
Taken from Rene Rondeau's book on page 212, "This very dramatic watch was sold in Europe and is rarely encountered in the United States. These European watches were unnamed and were instead catalogued by their reference number. The 64010-4 was identical to the 60007-4 except that is has an automatic movement with a date window at 3."
Presented here is the rarely seen European calendar model asymmetric Hamilton 64010-4 automatic watch in a yellow gold-plated case with a stainless steel back in beautiful condition. The refinished ivory colored dial features a fully functional date window at 3 o'clock and has a vertical striped surface. This timepiece sets and winds smoothly and is powered by a Hamilton 64 caliber automatic winding movement with 21 jewels that has been cleaned, oiled, and timed for 24 hours. The watch runs strong and has been fitted with a new acrylic crystal and brand new IW Suisse genuine alligator calf straps in brown. Along with the model number 64010-4, the outer back case reads: Antimagnetic, Stainless Steel Back, WaterProtected, ShockProtected. On the reverse side it is engraved with the Hamilton logo and 1155485. This asymmetric Swiss Hamilton measures approximately 34mm in width (excluding the crown) x 39mm from lug tip to lug tip
