The lineup includes distinct references: XS.3104 pairs a blue wave-textured dial with a steel bracelet, while XS.3101 has a black dial and cut-to-fit rubber strap. This is a specification-based overview; no physical watch was handled or independently tested.
What the 3100 Series includes
“3100 Series” refers to Luminox’s Pacific Diver Automatic family. The references share the core automatic platform, but dial and supplied strap differ. The XS.3104 product page describes a blue wave-textured dial and steel bracelet; XS.3101 is listed with a black dial and cut-to-fit rubber strap. Check the reference on the listing rather than assuming every 3100-series watch looks or wears the same.
Luminox’s Pacific Diver Automatic collection page says: “Enjoy the reliable function of the Pacific Diver Automatic’s Swiss-made Sellita automatic movement.” The collection page also covers the separate 3120 Pacific Diver and 3140 Pacific Diver Chronograph families; their movement or chronograph details should not be attributed to these 3100 models.

How the references differ
XS.3104: blue dial and steel bracelet
Luminox describes the XS.3104 with a blue wave-textured dial and stainless-steel bracelet. Its US product page displayed $1,825 when accessed in 2026. That is a dated official listing price, not a guaranteed current price or transaction price; check the XS.3104 product page for current price and availability.
XS.3101: black dial and rubber strap
The XS.3101 product page lists a black dial and cut-to-fit black rubber strap. The series sheet lists this reference at 105 g; the XS.3104 bracelet reference is listed at 180 g. Those are manufacturer-published figures, not weights independently verified here.
Rank #2
- LUMINOX - Since 1989, Luminox has been dedicated to creating watches that combine precision, durability, and functionality.
Midnight Mariner: a separate illumination treatment
The Midnight Mariner is a distinct variant, not a description of the standard blue and black dial models. Its product page specifies a white textured dial coated with Super-LumiNova and 16 LLT tubes. Keep these special dial-treatment details separate from the general series illumination claim.
Illumination and the water-resistance rating
Luminox’s 2024 series sheet says its Luminox Light Technology provides constant glow for up to 25 years in any light condition. This is the manufacturer’s duration claim. The Midnight Mariner’s Super-LumiNova dial coating is an additional variant-specific detail, as described above.

Rank #3
- Automatic Movement: Swiss SELLITA SW 200-1
- Luminous Performance: Glows Constantly for Up to 25 Years
- Case Material: Durable 316L Stainless Steel
- Crown Protection: Screw-In for Enhanced Security
- Crystal Protection: Sapphire with Anti-Reflective Coating
The 200 m / 20 ATM / 660 ft rating is also the manufacturer’s claim, with individual testing stated in Luminox’s 2024 sheet. It does not represent an independent test of this article’s sample, and no physical watch was tested here. Readers planning to use a watch for diving should consult Luminox’s guidance and follow applicable equipment and safety practices rather than treating a published rating as a substitute for inspection or dive training.
Fit and buying checks
- Confirm the exact reference. XS.3104 and XS.3101 differ in dial and supplied bracelet or strap; the collection also includes other families with different complications.
- Do not infer strap compatibility from width alone. Luminox lists a 24 mm strap width, but that measurement does not establish that every third-party strap will fit or suit a particular reference. Confirm attachment and reference compatibility before ordering.
- Check regional price, stock and warranty terms. The $1,825 XS.3104 listing was observed on Luminox’s US page in 2026 and may change. Luminox’s European product listing says its two-year warranty applies to purchases through official websites or authorized retailers; confirm the terms that apply in your region before buying.

What the published specifications do not establish
Manufacturer specifications identify the design and rated figures, but they do not establish measured accuracy, long-term reliability, comfort on a particular wrist, bezel feel, or real-world performance. No independent comparison or physical handling is available here, so those qualities should not be presented as tested conclusions.
