Tyrone
1955–1958 · 10k YGF / Stainless · Manual Wind
About the Tyrone
Made from 1955 through 1958, the Tyrone is an angular-cased Hamilton in a 10K yellow Gold Filled case with a stainless steel back, running either the caliber 747 or the later caliber 730 manual wind movement. Both are 17-jewel American-made movements, though the 730 added shock protection, making it a meaningful upgrade over the 747. The cushion-shaped silver dial carries applied gold numerals at 2, 4, 8, 10, and 12, with applied gold markers filling the remaining positions, and a subseconds register at 6 o'clock. The Tyrone is part of Hamilton's broader American-made dress watch lineup from the mid-1950s, a period when applied-dial construction was still the standard for models at this price point.
Finding a clean Tyrone today usually means navigating decades of storage, and the silver dial finish is the first place to look carefully. A lesser-known variant turns up occasionally with a silver dial, which reads differently under light and commands extra attention from collectors who track dial variations. The angular case shape gives the Tyrone a bit more character than many of its contemporaries, and examples with an unpolished case still showing original surfaces are worth seeking out.
From the Catalog
Hamilton marketed the Tyrone in 1955 with a 10K yellow gold-filled case, stainless steel back, and 10K gold numerals and markers, priced at $67.50 on bracelet or $59.50 on strap. For the mid-1950s, that placed the Tyrone solidly in Hamilton's mid-tier dress category, a well-made everyday watch rather than a showpiece.

What to Look For
| Dial | Examine the silver dial closely for separation, bubbling, or fading near the edges and around the numeral feet. The original finish is vulnerable to moisture and cleaning attempts, and damage is almost always irreversible. Also confirm whether the dial is the standard silver finish or the rarer silver variant, as they are not interchangeable between case configurations. |
| Crystal | Check for deep scratches or crazing on the crystal. A fogged or crazed crystal can scatter light across the dial and make condition harder to assess until it is replaced. |
| Movement | Wind the watch fully and let it run for several hours. If it is running on dried oil, it will often run erratically or stop before completing a full wind-down. Ask whether the movement is a caliber 747 or 730 and whether the watch has been serviced recently, as the 730 with shock protection is the more robust of the two. |
| Case | Look at the case edges and lugs for signs of heavy polishing, which will have softened the original angular lines. The gold-fill layer on the case wears at the lugs and high points first, so check those areas under magnification if possible. |
| Crown | Test the crown through winding and time-setting. It should wind smoothly and set without slipping. A crown that feels loose or strips during winding may indicate a worn stem or damaged crown threads. |
The Movement
The Tyrone was fitted with either the caliber 747 or the caliber 730, both 17-jewel manual wind movements made in Hamilton's Lancaster, Pennsylvania facility. The 730 is the later and preferable of the two, adding shock protection to the balance assembly, which makes it more resilient to everyday knocks. Both movements wind and set well when properly serviced and are known for reliable timekeeping.
