The Dan Henry 1970 is a vintage-inspired automatic diver-style watch built around a distinctive two-crown layout and an inner rotating timing bezel. Its 40 mm and 44 mm sizes offer different wrist footprints, but the available reviews do not establish a universal fit. The current official listing specifies a Seiko NH35 movement and 200 m water resistance; neither that rating nor the compressor-style design alone proves suitability for diving. At the official page’s $320 USD listed price on 8 October 2026, its appeal is strongest for buyers who want the look and functions, and who are comfortable with the crystal and crown trade-offs described below.
What is the Dan Henry 1970 Diver Compressor?
The 1970 is an automatic diver-style watch with a 60-minute inner rotating bezel. The crown at 2 o’clock operates the bezel; the crown at 4 o’clock sets the time, according to Dan Henry’s official product listing. Its two-crown arrangement gives it a compressor-style appearance. The available sources do not establish that it uses a historically authentic pressure-responsive compressor case, so “compressor-style” is the more precise description.
Dan Henry’s museum record dates the release to 20 September 2016 and records a production run of 1,970 pieces. It says the 44 mm model was the brand’s first automatic watch and the 40 mm version followed a year later. The record gives a sold-out date of 17 May 2019; that historical note differs from the official product page, which showed stock when accessed on 8 October 2026. Availability can change, so check the live listing rather than relying on either snapshot.
Should you choose the 40 mm or 44 mm version?
Case diameter is only one part of fit. Lug-to-lug length affects how far a watch spans across the wrist, while thickness affects how prominently it sits. The official page’s displayed dimensions specify the 40 mm version; Monochrome’s 2017 review supplies an approximate lug-to-lug measurement for the 44 mm version. The available sources do not provide a controlled wear comparison across wrist sizes.

Cameron Wong’s 2017 Time+Tide review says the 40 mm retained the tool-watch look while feeling more balanced on the wrist. That is Wong’s assessment, not a fit guarantee. Catellier describes the 44 mm as large. Use the measurements to judge the footprint you prefer; if possible, compare them with a watch you already find comfortable.
What are the dial, crystal and strap details?
The official specification block describes a matte black dial, a 60-minute inner bezel, LumiNova lume and a black-and-orange minutes chapter ring. Dan Henry lists orange, blue, black and white choices, along with date and no-date configurations. Confirm the details of the selected variant, since the displayed specification block describes a 40 mm listing rather than independently documenting every combination.
Rank #2

The crystal is sapphire-coated, double-domed mineral with anti-reflective treatment—not a sapphire crystal. Wong praised the domed, coated mineral crystal for the vintage-like distortions it creates. That effect may appeal to buyers who value character, but mineral and sapphire crystals are different materials; the official listing does not call this a sapphire crystal.
Dan Henry lists a black rubber strap, an easy-release strap arrangement and a three-slot canvas-and-genuine-leather watch roll among the included items. The 40 mm specification gives a 22 mm lug width, so a generic 22 mm replacement strap is the relevant starting size for that version. The 44 mm review reports 24 mm; check the exact variant before ordering a strap, and do not assume a particular third-party strap will fit.

What movement is inside, and what does it tell you?
The official product page specifies a Seiko Japan NH35 automatic movement with 24 jewels and a 41-hour power reserve. Monochrome also reports a 3 Hz beat rate. Wong and Catellier describe the NH35 favorably as a workhorse or reliable value-oriented movement. Those are reviewer assessments, not results from an accuracy, durability or longevity test of this particular watch.
The stated reserve is the official figure, not a promise of a particular daily accuracy. The cited sources provide no named test of this watch’s timekeeping, and no measured performance should be inferred from the movement description alone.

Does 200 m water resistance make it a real diver?
Dan Henry lists 20 ATM / 200 m / 660 ft water resistance, a screw-down crown and a screw-back case. Wong notes that the time-setting crown screws down, while both crowns do not; Catellier questions deep-water use because neither crown screws down. The apparent conflict is about which crown screws down: Wong identifies the time-setting crown as screw-down, whereas Catellier’s review raises concern about both.
The published rating is a specification, not evidence here of an independent dive test or a guarantee that a particular watch remains water-resistant after wear, impact or servicing. The sources do not establish dive suitability or safety from the rating alone. Anyone intending to use the watch underwater should confirm the current manufacturer guidance and the individual watch’s condition rather than treating its style or printed rating as a substitute for that verification.

Is the Dan Henry 1970 worth its listed price?
The official product page showed a $320 USD listed price and stock status when accessed on 8 October 2026. Both are time-sensitive; confirm the live price, variant availability, shipping and return terms before buying. The $250 price cited by Time+Tide and Monochrome belongs to their 2017 reviews and is not the current listed price.
At the listed price, the case for the 1970 is its combination of an automatic NH35, inner rotating bezel, two-crown design, multiple sizes and included strap and watch roll. The trade-offs are also concrete: its crystal is coated mineral rather than sapphire, the 44 mm version has a reported 24 mm lug width, and the crown configuration has prompted a reviewer’s concern about deep-water use. The official page states a one-year international warranty for material or workmanship defects and lists exclusions including straps and glass; check the current terms before purchase.
For context, the model’s 1,970-piece production run is a historical fact, not evidence of resale value or investment potential. The sources provide no resale study or performance test that would support those claims.
Who is the 1970 best suited to?
- Consider the 40 mm if its 45.7 mm lug-to-lug and 22 mm strap width match your preferences. Wong found this version more balanced, but that remains his subjective wrist impression.
- Consider the 44 mm if you want the larger case and are comfortable with the approximately 50 mm lug-to-lug and 24 mm strap width reported in Monochrome’s 2017 review.
- Look elsewhere or verify carefully if a sapphire crystal or independently established deep-water performance is essential to your purchase.
- Check the specific variant for date, color, dimensions, stock and current terms; the official listing includes multiple configurations.
These are fit and value judgments based on the published specifications and attributed reviews, not a personal hands-on, timing or pressure test of the watch.
