Sea-Scape
1959–1961 · 10k RGP / Stainless · Manual Wind
About the Sea-Scape
The Sea-Scape ran from 1959 through 1961, giving it a three-year production window that makes clean examples genuinely worth finding. It carries the caliber 671, a 17-jewel manual wind movement, in a round 10K yellow Rolled Gold Plate case with a stainless steel back. The dial comes in either black or white, both featuring embossed gold numerals and luminous markers with a pearled track, and a sweep seconds hand rather than a subseconds register. The Sea-Scape is the first in a short family that also includes the Sea Scape II and Sea Scape III, each building on this original design.
Finding one with the original embossed numerals and markers fully intact is the first thing to check, since those raised details can wear or pull away from the dial over time in ways that flat printed dials do not. The white dial version tends to show age more visibly through yellowing or spotting, while the black dial hides minor wear better but can lose its depth if it has been exposed to moisture. Hamilton originally offered the Sea-Scape on either a bracelet or a strap, and bracelet examples that still have the original hardware intact are a nice find.
From the Catalog
Hamilton marketed the Sea-Scape in 1959 with its waterproof rating as a selling point alongside the embossed numerals and pearled track dial, positioning it as a capable sport watch in a dressy package. It retailed at $65.00 on a bracelet or $55.00 on a strap, though it's worth keeping in mind that no vintage watch with an original waterproof rating should be trusted near water today.

What to Look For
| Dial | Look closely at the embossed gold numerals and markers. They sit raised from the dial surface and can come loose, chip, or wear down at the edges over decades. The luminous material in the markers often ages to a cream or brown tone, which is normal, but check for flaking or missing lume. On white dials, look for spotting or yellowing from moisture intrusion. On black dials, check for loss of depth or a milky haze, which can signal the same. |
| Crystal | The Sea-Scape uses a special crystal designed to accept a reflector ring, so a generic replacement may not sit or seal correctly. Confirm the crystal fits flush and that the reflector ring, if present, is intact and properly seated. Cracks or chips at the edges are common when the wrong crystal has been pressed in. |
| Movement | Lubricants in the caliber 671 break down over decades, and a movement running on dried oil is wearing itself out with every tick. Ask whether the watch has been serviced recently. A movement that runs but runs rough or inconsistently is often just in need of a proper clean and oil, but it should be addressed before trusting it for daily wear. |
| Case | The case is 10K yellow rolled gold plate over a base metal, with a stainless steel caseback. Check the high points of the case for worn-through plating, which shows as a darker or coppery tone at the lugs and edges. The stainless caseback can be tricky to open without the right tools, and evidence of prying attempts around the back lip is worth noting. |
| Crown | Pull the crown gently through its positions and check that it seats firmly when pushed back in. The caliber 671 has a known tendency for the set lever screw to work loose over time, which can cause the stem to pull out unexpectedly during time setting. If the crown feels loose or comes out too easily, have a watchmaker check that screw before using the watch. |
The Movement
The caliber 671 is a 17-jewel manual wind movement that Hamilton used across a range of dress and sport watches in this period. It winds from the crown, keeps time reliably when properly serviced, and drives a sweep seconds hand rather than a small subseconds register, which gives the dial a cleaner look. The gear train can be finicky to realign during reassembly, so it rewards a careful hand at the bench, but it's a dependable caliber when it's been properly maintained.
