Fratello’s fifth installment of its sleeper-watch series, published March 15, 2024, picked five pre-owned models that are less obvious choices from their respective brands: an Oris Star Diver, an Omega Seamaster Professional 300M, a Vacheron Constantin Overseas, an Ebel chronograph, and a Zenith El Primero Rainbow Flyback. The selection ranges from a 1960s diver to a colorful 1990s aviation chronograph. Here are the exact models and what makes each one stand out.
What Fratello means by a sleeper watch
In this installment, Fratello presents “forgotten gems”: models the author considers worthy of attention despite taking a backseat to more familiar watches from their brands. It is an editorial selection, not a standardized comparison or a market survey. The price figures below are estimates published by Fratello on March 15, 2024, not current valuations or offers.
Fratello’s five pre-owned sleeper watches
1. Oris Star Diver
Introduced in 1966, the Star paired a 36 mm stainless-steel case with Oris’s 25-jewel automatic caliber 645. Fratello points to its asymmetric date window, oversized crown, and vintage Oris logo as defining details. The article notes that original examples in decent condition can be difficult to find. Its March 2024 estimate was €1,000–€2,000; that historical range does not establish what a suitable watch costs today.
2. Omega Seamaster Professional 300M ref. 2230.50.00
This early-2000s Seamaster has a 41 mm steel case measuring 12.3 mm thick, a white-gold bezel insert, and a black wave-pattern dial. Inside is caliber 1120, with 23 jewels, a frequency of 28,800 vibrations per hour, and a stated 44-hour power reserve. Fratello’s March 2024 guidance started just below €3,000 and extended to slightly above €4,000; it is dated article guidance, not a current price range.

3. Vacheron Constantin Overseas ref. 42042
The ref. 42042 is the updated-movement version of the first-generation Overseas, introduced in 1996. It has a 37 mm steel case and integrated bracelet, and was offered with several dial colors. Fratello identifies its caliber as 1311 and says reinforcement of the mainplate made the movement 0.3 mm thicker, bringing its total thickness to 3.3 mm. The article’s March 2024 estimate ran from just under €10,000 to roughly €15,000, with €10,000–€13,000 described as the range for a good example. These are historical estimates, not a current valuation.
4. Ebel Le Modulor Chronograph ref. 5137241
The 40 mm ref. 5137241 combines an 18-karat pink-gold case with a two-tone white and copper dial. Fratello says the Le Modulor debuted in 1995 and describes its caliber 137 as based on the Lemania 1340, developed with 40 proprietary parts, and equipped with a “magic finger” winding system. The article reports COSC certification, a frequency of 28,800 vibrations per hour, and a 48-hour power reserve. Its March 2024 estimate was €7,000–€8,000; Fratello also said the pictured watch was available for €7,800 at the time. Neither figure verifies present availability or price.
5. Zenith El Primero Rainbow Flyback Chronograph ref. 02.0480.405
Zenith’s colorful aviation chronograph has a 40 mm steel case, a thickness of 12.6 mm, and the El Primero 405 flyback movement. Fratello says the French Air Force commissioned the model in 1995, but the original government budget was frozen; Zenith presented it to the public at Baselworld in 1997. The article’s pre-owned estimate was roughly €3,000–€4,500 at publication in March 2024, not a current market range.

The five picks differ substantially in age, material, size, movement, and complication, so the list is a starting point for identifying models—not a ranking of value or a guarantee that any particular example is a good buy. Four entries have exact references in Fratello’s article; the Oris is identified only as the Star Diver.
Rank #3
- Domed mineral crystal lens; light champagne dial with gold-tone hands and crystal accented markers
- Gold-tone adjustable link bracelet; fold over clasp with double push-button safety
- Inner band circumference: 7 inches
- Japanese quartz movement
- Case diameter: 36 millimeters
- Confirm the reference on the watch and its accompanying documentation, especially for the Omega 2230.50.00, Overseas 42042, Ebel 5137241, and Zenith 02.0480.405.
- Assess the individual watch’s condition and service history rather than relying on a model-level description or an old price estimate.
- Check what is included, the seller’s reputation, and the return terms before committing to a pre-owned purchase.
- For a less common vintage example such as the Oris, factor in how difficult it may be to find a well-preserved watch.
