Hands-On: The Zelos Spearfish Dual Time, Explained

The Zelos Spearfish Dual Time combines a grande date with an independently adjusted second-time display and rotating 24-hour map disc. Here are its specs, variants and reviewer impressions.

The Zelos Spearfish Dual Time pairs a large date with a separate second-time display built around a rotating 24-hour map disc. Zelos lists a 40 mm case, 47 mm lug-to-lug, 100 m water resistance and a Sellita SW300 with TT651 module. Its notably slim stated case measurement excludes the domed crystal, and reviewer impressions vary by material and example.

How the dual-time display works

The dial’s second-time display is not the usual GMT arrangement in which the wearer jumps the local hour hand. Instead, it has its own pair of hands, which Zelos says can be adjusted independently and make a 12-hour rotation. Beneath them, a world-map disc turns on a 24-hour scale, so the display can also indicate day or night in the selected second zone.

Fratello’s Thor Svaboe described the register as a two-hand 24-hour GMT display and reported that its 24-hour hand can be adjusted quickly via the crown. The distinction matters: this is a dedicated secondary display, not a conventional independently jumping local-hour GMT mechanism.

The case’s 10 mm figure is not directly comparable with a measurement that includes its prominent box crystal. The additional reviewer measurements above are useful context, but they refer to specific examples and sources.

Big date, open dial and readability

The grande date uses two separate date wheels to create a larger numeral display. The world-map disc and second set of hands add visual activity, especially on open-worked dial versions. Svaboe praised the complexity created by the big date and lumed map register. Antzoulis, writing about the forged-carbon Moonscape he wore for a little over a week, said the date numerals on his example were not consistently aligned. That is an observation about his sample, not evidence of a line-wide fault.

Case materials and dial variants

Zelos lists titanium cases hardened to 1200 HV and forged-carbon cases. The titanium versions come on a titanium bracelet; the forged-carbon variants are listed with a canvas leather strap and PVD buckle.

The official collection page lists these variants:

  • Titanium: Meteorite, Spark, Ocean Blue, Sky Blue and Gunmetal.
  • Forged carbon: Moonscape and Supernova.

The Meteorite dial is cut from Muonionalusta meteorite, and Zelos says each slice has a unique structure. The collection page also identifies solid-dial choices including CNC guilloché Gunmetal and Meteorite, alongside the more open-worked designs. See the Zelos Spearfish collection and the Meteorite model listing for the manufacturer’s current descriptions.

What reviewers reported on the wrist

Titanium: comfort and a slim profile

Thor Svaboe’s Fratello review, published April 7, 2024, describes the 40 mm watch as comfortable on his medium wrist. He reported a 105 g sized titanium example and measured 12.5 mm including the box sapphire. He also praised the dial’s visual complexity, writing: “I have thoroughly enjoyed the Zelos Spearfish Dual Time, which marks the next bold chapter for Elshan Tang’s brand.” These are his impressions of the example he reviewed.

Forged carbon: low weight, with a date-alignment caveat

Chris Antzoulis’s Worn & Wound review, published May 6, 2024, covers a forged-carbon Moonscape worn for a little over a week. He reported that it weighed 56 g on its strap and explained how the crown adjusts the second-zone display. He also criticized inconsistent alignment of the big-date numerals on that reviewed example. His weight and alignment observations should not be generalized to the titanium models or every production watch. Read his Worn & Wound review.

Price and availability

Zelos’s collection page displayed a price of $2,199 USD for listed Spearfish Dual Time variants when accessed on October 8, 2026; several listings were marked sold out at that time. The Meteorite listing also showed $2,199 and sold-out status. Prices and stock can change, so check the current Zelos collection page for the latest listing.

The $1,849 USD figure reported by Fratello and Worn & Wound was the 2024 launch price, not the current listed price. Fratello reported availability beginning April 8, 2024. The current price and the historical launch price refer to different dates.

Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply.
