Vintage Watch Hunting on eBay: Three Grails Worth Tracking

For serious vintage watch collectors across Asia, eBay remains one of the most democratised hunting grounds for undervalued mechanical horological treasures — provided you know exactly what to look for. This week, three listings caught the attention of seasoned collectors: a striking Wittnauer chronograph with genuine mid-century provenance, a Seiko diver that sits comfortably in the lineage of one of Japan's most celebrated tool-watch traditions, and a Longines Comet that challenges conventional taste in the best possible way. Current asking prices range from approximately USD 450 to USD 2,200, with auction-style listings on the lower-end pieces attracting bid activity that suggests the market for these tiers remains buoyant and competitive.

The Wittnauer Chronograph: American Roots, Universal Appeal

Wittnauer is a name that deserves far more respect than it typically receives at auction. Founded in New York in 1880 and operating as a sister brand to Longines through much of the twentieth century, Wittnauer produced a range of chronographs and dress watches that shared movement DNA with far more expensive Swiss stablemates. The eBay listing in question features a Wittnauer chronograph from the late 1960s, powered by a Valjoux 92 movement — a column-wheel calibre with a strong reputation for longevity and repairability. The current asking price sits at approximately USD 780, which represents meaningful value when comparable Valjoux 92-equipped chronographs from better-known Swiss houses routinely clear USD 3,500 to USD 6,000 at Antiquorum or Phillips Geneva. For Hong Kong and Singapore collectors building a reference collection of mid-century American-market Swiss chronographs, Wittnauer offers a credible entry point with genuine movement quality and period-correct aesthetics — panda dials, pump pushers, and all.

Condition on this particular piece is described as honest rather than pristine: the case shows appropriate wear consistent with its age, the dial has developed a warm patina without any significant spotting, and the original bracelet is absent — replaced with a period-correct leather strap. Sellers who document wear honestly tend to attract more sophisticated buyers, and this listing reflects that ethos. Provenance is listed as an estate purchase in New Jersey, with no subsequent service records, meaning a collector should budget an additional USD 200 to USD 350 for a competent movement service before daily wear.

Seiko Diver: The Canonical Japanese Tool Watch

The Seiko diver category needs little introduction to Asian collectors, but this particular listing — a reference 6105-8110 from approximately 1972 — represents one of the more collectible chapters in the brand's dive watch history. The 6105 calibre, with its distinctive cushion case and cathedral hands, was famously worn by Martin Sheen in Apocalypse Now, a provenance detail that has done considerable work in pushing Western collector interest toward this reference over the past decade. Current eBay asking price for this example is USD 2,200, which is on the upper end of the current trading range for unrestored 6105 examples; comparable pieces sold through Catawiki in 2024 averaged EUR 1,650 to EUR 1,950, while a particularly clean example with box and papers cleared JPY 320,000 at a Shinbashi dealer in Tokyo last autumn. The dial on this listing shows the classic matte black finish with no visible fading, and the rotating bezel insert retains strong lume pip definition — both indicators of a watch that has been stored rather than heavily used.

For Japanese domestic market collectors, the 6105 carries additional significance as a piece of export-era Seiko history — these watches were manufactured for international markets and are now returning to Japan through the secondary market at premiums that reflect both nostalgia and genuine scarcity. Serious collectors should note that movement condition on unserviced examples from this era can vary considerably; the 6105 calibre is robust but benefits from fresh lubrication after fifty-plus years. Budget accordingly.

Longines Comet: The Contrarian's Choice

The Longines Comet is not a watch for collectors who prioritise conventional beauty. Produced in limited numbers during the early 1970s, the Comet features an asymmetric tonneau case with an integrated bracelet design that reads as genuinely experimental — closer to a piece of sculptural jewellery than a conventional dress watch. The movement is a Longines calibre 431, a reliable automatic with a 42-hour power reserve and a date function. The eBay listing presents an example in yellow gold-fill with the original bracelet intact, priced at USD 450 — a figure that seems almost wilfully modest given that Longines signed pieces with original bracelets from this period are increasingly difficult to source complete. Reference comparisons are instructive: a Longines Conquest with original bracelet in similar condition sold for USD 680 on Chrono24 in March 2025, and a Wittnauer Ultra Slim from the same era cleared USD 520 at a Chicago estate auction. The Comet, by contrast, offers a more distinctive design statement at a lower entry price — which is precisely the kind of asymmetry that sharp collectors exploit.

For Asian collectors with an eye on the broader 1970s avant-garde Swiss watch movement — a category that includes Enicar, Favre-Leuba, and Movado's more experimental references — the Longines Comet represents an accessible and visually arresting addition. The brand's heritage, the movement quality, and the bracelet integrity combine to make this a credible long-term hold rather than a speculative flip.

Market Insight: Why These Three Matter Together

What unites the Wittnauer, the Seiko 6105, and the Longines Comet is a shared position in the secondary market: all three occupy the USD 450 to USD 2,200 range that represents the most active tier of vintage watch collecting globally. This is the segment where genuine horological knowledge creates genuine advantage — where a collector who understands movement calibres, case metallurgy, and period-correct dial typography can consistently acquire undervalued pieces ahead of broader market recognition. Asian collectors, particularly those based in Japan, South Korea, and Singapore, have demonstrated sophisticated taste in exactly this tier over the past five years, with Japanese collectors in particular driving renewed interest in export-era Seiko references and mid-century Swiss tool watches. For collectors building a reference library of mechanical watches across multiple traditions — American-market Swiss, Japanese domestic, and European avant-garde — these three pieces offer a coherent and defensible collecting thesis at a combined outlay of under USD 3,500.

Frequently Asked Questions

What makes the Seiko 6105 more valuable than other vintage Seiko divers?

The 6105 reference occupies a specific sweet spot in Seiko's dive watch history: it predates the more widely produced 6309 and benefits from a distinctive cushion case design, cathedral hands, and a cultural reference point through its appearance in Apocalypse Now. These factors combine to sustain collector demand and price premiums relative to comparable Seiko divers from the same era.

Is Wittnauer a legitimate Swiss watch brand or a secondary label?

Wittnauer is a fully legitimate brand with roots dating to 1880 in New York. Through its long association with Longines, Wittnauer had access to high-quality Swiss movements including Valjoux chronograph calibres. It is best understood as a market-tier brand rather than a secondary label — positioned for the American mass-luxury market rather than the Swiss prestige segment, but built with genuine horological substance.

How should Asian collectors approach eBay for vintage watch purchases?

Due diligence is essential. Prioritise sellers with strong feedback histories and detailed condition photography. Request additional images of the movement if possible, and verify reference numbers against published databases such as Ranfft or Caliber Corner. Factor in import duties applicable to your jurisdiction — Hong Kong collectors face no import duty on watches, while Singapore applies GST at 9% on declared value.

What is the current appreciation trend for 1970s avant-garde Swiss watches like the Longines Comet?

The broader category of experimental 1970s Swiss watches has appreciated approximately 35 to 55 percent over the 2019 to 2024 period, driven by collector fatigue with over-documented references and renewed interest in design-forward pieces. The Longines Comet specifically remains underappreciated relative to comparable pieces from Enicar or Universal Genève, suggesting potential for continued upside as collector attention broadens.

Should I service a vintage watch before or after purchasing it on eBay?

Always negotiate price with the assumption that a service will be required. For movements over 30 years old, budget between USD 150 and USD 400 depending on complexity and your chosen watchmaker. A pre-purchase service is not feasible in most eBay transactions, so focus instead on dial and case condition as visible proxies for overall care history, and treat movement service as a standard post-purchase cost of ownership.
