The DOXA uses an automatic ETA 2824-2 at 4 Hz / 28,800 vph with a 38-hour power reserve, which is a proven, well-established workhorse spec. The Longines uses an automatic movement at 3.5 Hz / 25,200 vph with a notably longer 72-hour power reserve, but the caliber is not listed, so its technical specifics are incomplete here. On paper, Longines offers the more convenient reserve, while DOXA offers a more clearly identified movement and a more conventional high-beat rhythm. Serviceability and long-term reliability are easier to infer for the DOXA because the caliber is listed, but the data does not support a firm accuracy or robustness comparison beyond general movement architecture. Winner: Tie
The DOXA is 42.5 mm across, 13.65 mm thick, 44.5 mm lug-to-lug, and 194 g, so it has substantial wrist presence but a very short span that helps it wear more compactly than the diameter suggests. Its existing wearability notes explicitly say it feels smaller and more balanced than the specs imply, aided by the cushion case and beads-of-rice bracelet. The Longines is slightly smaller in diameter at 42 mm and thinner at 12.85 mm, which helps comfort, but its 50.1 mm lug-to-lug is much longer and likely makes it wear larger across the wrist. No weight is listed for the Longines, but the longer footprint suggests the DOXA is the easier pick for smaller wrists, while the Longines may suit medium-to-larger wrists better if the wearer can accommodate the span. Winner: DOXA
The DOXA is the more overt tool watch: orange dial, Super-LumiNova, sapphire with AR coating, date display, helium escape valve, 1,200 m water resistance, and a bezel with a no-decompression dive calculator. Those specs make it outstanding for diving credibility and highly legible in demanding conditions, though the design is more specialized and the large clasp and heavy build may reduce subtle everyday versatility. The Longines has a black grained dial with painted Arabic numerals and indexes, Swiss Super-LumiNova, sapphire crystal with anti-reflective coating on both sides, 300 m water resistance, no date, and an internal turning diving flange, giving it a cleaner, more restrained daily profile. It is clearly practical for water use and easier to style broadly, while DOXA is the stronger dedicated dive instrument. Winner: Tie
At $2,190 MSRP, the DOXA is materially less expensive than the Longines at $4,100 MSRP, which gives it a strong value advantage on entry cost alone. The DOXA also brings a distinctive heritage signal: the SUB line’s professional-diving roots, the helium escape valve story, and a cult following built around unmistakable design. The Longines carries strong brand heritage as well, but that context is not expanded in the provided data, so its premium is harder to justify strictly from the listed specs. In ownership terms, DOXA looks like the more straightforward buy for collectors who want authenticity and uniqueness without paying the higher sticker price; Longines asks more but offers a more refined, less polarizing package. Winner: DOXA
