Wynn
1955–1956 · 10k Yellow Gold Filled · Manual Wind
About the Wynn
The Wynn appeared in a single catalog year, 1955, as part of Hamilton's Medallion family. It runs on either a caliber 747 or caliber 730, both 17-jewel manual wind movements, housed in a 10K yellow Gold Filled cushion case. What sets the Wynn apart visually is its dial: a sterling silver surface fitted with applied gold numerals in 18K gold, a level of material refinement that was explicitly called out in Hamilton's original marketing. The Medallion line positioned itself as Hamilton's dressier domestic offering, and the Wynn fits that character well.
Silver dials are genuinely different to care for than the lacquered or matte silver dials common on other Hamiltons of the period. The surface can patina attractively over decades, but it's also vulnerable to moisture and improper cleaning, so finding one with a clean, intact dial is meaningful. The applied 18K gold numerals appear at all positions except 6 o'clock, where a subseconds register sits, and on a good example those numerals will still show their original depth and warmth against the silver dial.
From the Catalog
Hamilton described the Wynn in 1955 as offering a 10K yellow gold-filled case with 18K gold numerals on a sterling silver dial. It retailed for $75.00 on a strap or $82.50 on a bracelet, with those two configurations assigned separate model numbers.

What to Look For
| Dial | The silver dial is the heart of this watch, and it shows its age honestly. Look closely for separation, bubbling, or fading around the edges and near any moisture entry points. Cleaning attempts can damage the finish in ways that are not reversible, so discoloration or uneven patina may signal prior mishandling. The applied 18K gold numerals should sit flush and even with no missing pieces. |
| Crystal | Check for deep scratches or crazing. A worn crystal is replaceable, but make sure any replacement fits the cushion case shape correctly and is not sitting proud of the bezel or pressing on the dial beneath. |
| Movement | Confirm whether the movement is a caliber 747 or caliber 730, as they are not interchangeable. Wind the watch fully and let it run for several hours. Dried oil in either caliber can cause erratic timekeeping or outright stopping under load, so inconsistent running is a strong signal that a service is due. |
| Case | The 10K yellow gold-filled cushion case can show brassing at high-contact points, particularly on the lugs and case back edges. Some wear is expected on a watch of this age, but heavy brassing that exposes the base metal underneath affects both appearance and long-term durability. |
| Crown | Pull the crown gently through its positions and confirm it winds smoothly and sets the hands without slipping. A loose or damaged crown on a watch this age may indicate a worn stem or stripped threads, either of which adds to the cost of getting it running properly. |
The Movement
The Wynn houses either a caliber 747 or a caliber 730, and it's worth confirming which is present before purchase. Both are 17-jewel manual wind movements, but they are distinct calibers with different parts. Hamilton used both in this era across several models, and they are not interchangeable within the case.
