About the Auto Date Ventura
Made from 1974 through 1977, the Auto Date Ventura is a stainless steel rectangular-cased watch that connects two of Hamilton's most recognizable threads: the iconic Ventura shape and the Auto Date family of automatic movements. The catalog listing paired a blue dial with either a strap or bracelet, priced at $130 and $145 respectively. Production lasted a multiple years, making examples relatively uncommon today.
The blue dial is the first thing to evaluate on any example you come across, since blue dials from this era can fade unevenly or develop a patchy appearance if they've seen moisture or prolonged UV exposure. A clean, even blue with no spotting or peeling is what you're hoping for. The stainless steel case holds up well over time, but the rectangular shape means any dings or polishing on the lugs will be immediately obvious, so condition on the case corners matters.
From the Catalog

What to Look For
| Dial | Look closely at the blue dial under good lighting. Uneven color, cloudiness near the edges, or any separation near the chapter ring are signs of past moisture intrusion. A dial in honest original condition, even with minor age, is preferable to one that's been touched up. |
| Crystal | Check for chips or deep scratches, especially along the edges where the crystal meets the bezel on a rectangular case. A properly fitting crystal matters more here than on a round watch because an ill-fitting replacement can sit proud or leave gaps. |
| Movement | On a watch this age, dried oil creates enough friction to stop the movement or cause it to run erratically, even if it appears to be running. Ask about service history, and if it's unknown, budget for a service before putting the watch into regular use. |
| Case | The rectangular stainless case should show its original finishing on the flat surfaces. Over-polishing softens the edges and corners in a way that's hard to reverse, so look for a case that still has some crispness to it rather than one that's been buffed smooth. |
| Crown | Wind the crown and feel for any roughness or slipping. On a watch that may have sat unserviced for years, the winding action is a useful early indicator of what's happening inside. |
The Movement
The Auto Date Ventura runs on Hamilton's Quick Change caliber referenced in the catalog listing as Q/C I, an automatic movement with a date complication that advances via a quick-set mechanism. Automatic movements from this period rely on a rotor to wind the mainspring through wrist motion, but they still benefit from occasional hand-winding to keep everything lubricated and running smoothly. A movement in good service condition will wind freely, set cleanly, and keep reasonable time.
