Proxima PX1748 — 39mm Black and Gold Dive Watch with Miyota 9015

39mm • 316L Stainless Steel • Miyota 9015 or 90S5 • 100m Water Resistance • Bubble Sapphire Crystal • Visible Movement Caseback

The PX1748 is built around a colour combination that the watch market has never moved away from for good reason: matte black dial, gold-toned handset and indices, ceramic bezel with gold numerals. The combination reads simultaneously as vintage and contemporary — warm enough to feel character-driven, restrained enough to work across a wide range of outfits and contexts.

What elevates the PX1748 beyond that colour story is the execution. The gold-outlined triangular and circular indices are applied — not printed — giving them physical relief above the dial surface that creates depth when light catches them. The arrow handset is brushed gold-tone with BGW9 lume inserts. The bubble sapphire crystal sits above all of it with a domed profile that adds visual height and creates a vintage watch character that flat crystals cannot replicate. Turn the watch over and the Miyota 9015 is fully visible through the sapphire caseback — 24 jewels, Miyota Co. engraving readable through the glass.

The Dial — Why This Combination Works

The matte black surface has a subtle texture — not glossy, not flat matte, but a fine grain that catches light without glare. Against this background, the applied gold-outlined indices create a dial that reads as genuinely handcrafted rather than machine-printed.

The index design uses two shapes in alternation: circular dots at the hour positions and triangular arrowhead indices at 12, 3, 6, and 9. Each is gold-rimmed with a BGW9 lume fill — large enough to glow prominently in the dark while reading cleanly in daylight. The lume shot confirms the coverage: every index and both hands emit simultaneously at consistent brightness, creating a complete and evenly lit dial face in darkness.

The gold arrow handset is the defining detail. The hour and minute hands use a broad arrow format with brushed gold finishing and rectangular BGW9 lume cells at the center. The seconds hand is a slim gold needle. The combination is legible at a glance while being visually interesting enough to hold attention under close examination.

The black ceramic bezel insert carries gold-toned numerals — consistent with the dial’s warm colour language. The triangle marker at 12 o’clock is also gold-toned, tying the bezel directly to the dial design rather than treating it as a separate functional element.

If you prefer a bold colour dial instead, the Proxima PX1752 teal spiral dial uses the same Miyota 9015 movement with a completely different aesthetic.

Bubble Sapphire Crystal and Visible Caseback

The PX1748 uses a bubble sapphire crystal — a domed convex profile rather than flat sapphire. The dome creates a characteristic vintage visual effect: the dial appears to float under a magnifying lens, adding visible height that makes the watch read as more substantial than its 10.95mm thickness suggests. AR coating reduces glare from the curved surface.

The caseback is screw-down with a sapphire crystal window — the Miyota 9015 rotor is visible and the inscription is readable in the caseback image: Automatic Movement, Sapphire Crystal, Water Resistant 100m, 9015, 24 Jewels, Miyota Co. For any buyer interested in movements, the visible 9015 is a daily confirmation of what is powering the watch.

For a watch with a flat sapphire crystal and 200m depth rating, see the Proxima PX1703 white dial with PT5000 or Swiss SW200 movement.

Movement Options: Miyota 9015 vs 90S5

Miyota 9015 — 24-jewel automatic manufactured by Citizen’s Miyota division in Japan. Runs at 28,800 vph for smooth sweep, 42-hour power reserve, hacks and hand-winds. One of the most respected movements in the independent watch market for its combination of smooth motion, reliability, and global serviceability. The caseback image confirms the 9015 specification directly.

90S5 — Miyota’s 9015 variant with a decorated rotor and enhanced finishing. Same core movement architecture and performance characteristics as the 9015, with visual upgrades to the rotor that are appreciable through the sapphire caseback window.

Chinese 9015 — Domestically produced movement to the same specification. Reliable daily performer at the most accessible price point.

Full Specifications

Case, Bracelet and Finishing

At 39mm with a 46.5mm lug-to-lug and 10.95mm thickness, the PX1748 sits in a compact, wearable footprint. The slim profile combined with the bubble crystal creates a watch that reads as more substantial visually than it feels on the wrist.

The case finishing combines brushed surfaces on the flanks and lugs with polished bevels at the lug edges — a combination that adds visual quality without the maintenance demands of a fully polished case. The crown carries the Proxima engraved logo and the knurling is substantial enough to operate without fingernail assistance.

At 158 grams the PX1748 is the most substantial watch in the Proxima lineup reviewed here — the bracelet construction is solid rather than hollow-link, contributing to both weight and quality feel. Quick-release spring bars allow strap changes without tools. The micro-adjustable clasp allows half-size fit adjustment without link removal.

How the PX1748 Compares to Other Proxima Models

Proxima PX1749 — PT5000 movement, spiral vortex engraved dial, 200m water resistance, ceramic bezel, steel bracelet. The deeper-rated and more technical-looking option in this price range. Best for buyers who want 200m depth rating and a distinctly modern, textured dial character.

Proxima PX1752 — Same Miyota 9015 movement and bubble sapphire crystal as the PX1748, teal spiral dial, matched leather strap, 100m. Best for buyers who want colour-matched dial-to-strap cohesion and a warmer-weather aesthetic.

Proxima PX1703 — PT5000 or Swiss SW200, white enamel dial with orange chapter ring, sapphire bezel insert, 200m, steel bracelet. Best for buyers who want maximum depth rating and the option of a Swiss-manufactured movement.

The PX1748 is the choice when you want the Miyota 9015 visible through a sapphire caseback, a classic black-and-gold dial combination, and a compact 39mm profile — all in one package.

Who the PX1748 Is For

Buyers who want warmth in a black dial watch. Most black dial dive watches pair with silver indices and white lume. The PX1748’s gold elements give it a character that is immediately distinguishable from standard tool watches. Browse the full men’s watches category for the complete range.

Miyota 9015 enthusiasts who want to see the movement. The sapphire caseback puts the 9015 on display daily. For buyers who chose the watch for the movement, that visibility is part of the ownership experience.

Vintage aesthetic buyers. The bubble crystal, arrow handset, circular dot indices, and gold-on-black colour scheme draw on mid-century professional dive watch design language — entirely a Proxima design, delivered with consistent detail throughout. For rings and accessories that complement this aesthetic, see the men’s rings collection at Jewelry Addicts.

Slim-profile buyers. At 10.95mm the PX1748 sits comfortably under a cuff and does not create a raised transition at the wrist edge that thicker dive cases can produce.

FAQ

What is the difference between the 9015 and 90S5 movement options? Both are Miyota-manufactured Japanese automatic movements at 28,800 vph with 42-hour power reserve, hacking and hand-winding. The 90S5 features a decorated rotor visible through the sapphire caseback. Performance is identical — the choice is about the visual appearance of the rotor.

What is a bubble sapphire crystal? A domed convex sapphire profile rather than flat. It creates a vintage character — the dial appears to sit under a magnifying lens — and adds visual height to the watch profile. AR coating maintains legibility by reducing glare from the curved surface.

Is 100m water resistance enough for swimming? Yes — appropriate for swimming, snorkeling, and surface water sports. The screw-down crown provides pressure integrity for regular water exposure. For scuba diving depth ratings, see the PX1749 and PX1703 rated to 200m.

Can I change the strap? Yes — quick-release spring bars allow 20mm strap changes without tools. Browse men’s leather belts and accessories at Jewelry Addicts to complete the look.

What does the micro-adjust clasp do? It allows small fit adjustments without removing bracelet links — practical for wrist size changes with temperature and daily activity.

Is the gold tone PVD coated? Yes — PVD (physical vapour deposition) bonds the gold finish to the metal surface, making it significantly more durable than plating. It resists daily wear and skin oil contact without peeling.
