About the Day 'N Date 6000
The Day 'N Date 6000 was produced from 1969 through 1971, part of Hamilton's Day 'N Date family of automatics that combined day and date complications in an accessible, everyday package. The case is 10K yellow Rolled Gold Plate, giving it a warm tone that has aged well on surviving examples. No caliber data has been confirmed for this specific reference, so movement details are addressed separately in service documentation.
Rolled Gold Plate cases from this era vary quite a bit in how they've held up, look closely at the lugs and case edges, where wear cuts through the gold layer first and exposes the base metal underneath. The Day 'N Date complications also give you a functional checklist right away: both the day and date displays should be advancing cleanly and snapping over crisply at midnight, not creeping or stalling.

What to Look For
| Dial | Check for moisture damage, fading, and any separation or flaking around the hour markers. Dial condition is one of the harder things to reverse on a watch like this, so take a close look before committing. |
| Crystal | These would have left the factory with a plastic crystal. Deep scratches can be polished out, but a badly craized or chipped crystal needs replacement, originals are gone, but correct replacements are available. |
| Movement | Ask about service history. Dried oil in an automatic that has been sitting is a real concern, enough friction buildup will stop the movement entirely, and a watch that runs in-hand but stops when worn is a common sign. Budget for a full service if history is unknown. |
| Case | The 10K RGP case wears through at the lugs and high edges over time. Check those areas in good light. Some honest wear is expected on a watch this age, but deep wear that exposes base metal will not polish back. |
| Crown | Work the crown through all positions. It should pull out cleanly to set the day, date, and time without sticking or feeling gritty. A worn or damaged crown on a vintage automatic is an easy fix, but worth confirming before purchase. |
