White dial with gold-tone markers: The white dial version uses warm gold-tone triangle markers — creating a vintage instrument character. The gold markers against white create the warmer, more historically-referenced tone of mid-20th century military and professional watches.
Black dial: The black dial uses the same marker layout with stronger contrast — clean, legible and the more modern of the two.
Field-Dive Character
The SF751’s dial design draws from the field watch and dive watch traditions simultaneously — a combination sometimes called “field-dive”:
Field watch elements: Three-hand simplicity, Arabic numerals at key positions (12, 9, 6), clean legibility-first dial, no additional complications or decorative elements.
Dive watch elements: 200m water rating, screw-down crown, screw-in caseback, luminous hands and markers, robust case construction.
The result is a versatile sport watch appropriate for both land and water use without the visual bulk of a full dive instrument.
Triangle Hour Markers
Applied triangular markers at the non-numeral hour positions create the specific visual language of mid-20th century professional instruments. The triangle at 12 o’clock is the primary orientation marker — the same role as the triangle pip on a dive bezel, here integrated into the dial itself.
SF751 in the Steelflier NH35 Range
Three Steelflier NH35 automatics at Jewelry Addicts:
| Model | Case | Bezel | Character | Weight (no strap) |
|---|---|---|---|---|
| SF751 (this page) | 40mm / 14mm | Fixed — plain | Clean field-dive | 78g |
| SF783 | 41mm / 13.1mm | Ceramic rotating | Sport diver | 85g |
| SF752 | 45mm / 15.2mm | Steel rotating | Oversized diver | 120g |
Choose SF751 for the simplest, cleanest field-dive design with white dial option. Choose SF783 for the ceramic rotating bezel and luminous bezel scale. Choose SF752 for the maximum case size and BGW9 lume.
Strap Weights
| Strap | Total weight |
|---|---|
| Leather (black or brown) | 90g |
| Nylon | 107g |
| Stainless steel bracelet | 178g |
The SF751 is the lightest Steelflier at 78g without strap — 7g lighter than the SF783 and 42g lighter than the SF752. On leather at 90g it is among the lightest 40mm dive-specification automatics in the range.
Who Is the Steelflier SF751 For?
The SF751 is built for:
- Clean field-dive buyers who want the most minimal and uncluttered Steelflier dial — no tachymeter, no bezel markings, no colour accents
- White dial buyers who specifically want the warm gold-tone triangle marker version on a 200m NH35
- Lightweight buyers who want the lightest Steelflier at 40mm/90g on leather
- Buyers who want the NH35 200m specification without the visual complexity of the SF783 or SF752
How It Compares
vs. Steelflier SF783 — SF783 has ceramic rotating bezel, luminous bezel scale and red date window at 41mm/13.1mm. SF751 has fixed plain bezel, clean dial and white dial option at 40mm/14mm. SF751 is quieter; SF783 is more feature-complete for diving.
vs. San Martin SN007G V4 — San Martin uses NH35A at 41mm/200m with aluminium rotating bezel. SF751 uses NH35 at 40mm/200m with fixed plain bezel. Both are clean NH35 field-adjacent divers — San Martin has the functional rotating bezel; SF751 has the cleaner no-bezel-markings character.
vs. Baltany S182019 Field Watch — Baltany uses NH35 at a smaller case for the field watch aesthetic at 50m. SF751 uses NH35 at 40mm with 200m. SF751 shares the field watch visual but delivers genuine dive water resistance.
