Specht & Söhne Reversible Watch SP0028 — Ronda 751 Swiss Quartz, Flip Case, 50m

Specht & Söhne Reversible Watch SP0028 — Ronda 751 Swiss Quartz, Flip Case, 50m

The Specht & Söhne SP0028 is a Swiss Ronda 751 quartz reversible watch — the rectangular 316L stainless steel case rotates on its lugs to reveal two distinct faces. One face shows the watch dial with Roman numeral or index markers; the other shows a polished decorative backplate. Sapphire crystal, genuine leather strap tapering from 18mm to 16mm, 50m water resistance. Available in three double-face configurations: Double-Face-1, Double-Face-2, Double-Face-3, each presenting a different combination of dial styles and strap colour.

Key Specifications

Variants — Three Double-Face Configurations

The three configurations differ in the combination of faces and strap colour:

Double-Face-1: A specific dial and reverse-face combination — check the product listing image for the exact face pairing. Black strap.

Double-Face-2: A different dial/reverse combination. Blue strap.

Double-Face-3: A third face combination. Brown strap.

Dial styles across the three variants include: black Roman numeral, white Roman numeral, silver index and mother-of-pearl style decorative reverse face options. Each Double-Face configuration offers a specific pairing — the versatility comes from the two distinct looks in a single watch rather than simply from colour choice.

The Reversible Case Mechanism

The SP0028’s rotating case is the defining feature — the entire case, including the crystal and movement, pivots 180 degrees on the lug axis to present the reverse face outward.

How to operate: Press the crown side of the case inward — this releases the spring mechanism holding the case in position. The case rotates freely to the reverse face, where the spring re-engages and locks it in place. The movement inside does not stop during the flip; the watch keeps running throughout.

What the reverse face shows: Depending on the variant, the reverse face presents either a polished blank steel plate (for the most minimal look) or a decorative face with mother-of-pearl style finish. The reverse is a complete visual alternative — not just a caseback.

Historical context: Reversible watches were developed in the 1930s primarily for sports protection — flipping the crystal face inward during polo or other contact sports prevented dial damage. The Jaeger-LeCoultre Reverso (1931) is the most famous example. Modern reversible watches use the same mechanism for versatility rather than protection — the ability to wear a single watch in two distinct configurations. The SP0028 brings this mechanism to an accessible price at a compact rectangular scale.

Ronda 751 Swiss Quartz

The Ronda 751 is a Swiss-manufactured quartz caliber — a thin, reliable movement produced by Ronda AG of Lausen, Switzerland. Swiss quartz movements from Ronda are used across the watch industry from affordable to mid-range dress watches. The 751 provides dependable accuracy (approximately ±15 seconds/month) with multi-year battery life. For a reversible watch where movement thinness contributes to the case’s ability to flip cleanly, a Swiss quartz caliber is appropriate — mechanical movements at equivalent thinness and price are not available.

18mm Tapering Strap

The strap tapers from 18mm at the case to 16mm at the buckle — a traditional dress watch strap profile. The taper creates a lighter visual weight at the buckle end, consistent with historical rectangular watch strap design. The tapering means the strap sits flat against the wrist at the buckle rather than bunching. Replacements should be 18mm at the case end; confirm the taper specification with any aftermarket strap supplier.

Who Is the Specht & Söhne SP0028 For?

The SP0028 is built for:

• Reversible watch buyers who want the flip mechanism at an accessible price — genuine rotating case in Swiss quartz at under $200
• Buyers who want two distinct watch aesthetics in a single piece — minimal polished reverse vs Roman numeral dial, without carrying two watches
• Small rectangular case buyers — 23.8–24.5mm × 32.4mm is among the most compact dress watch profiles available
• Roman numeral dress watch buyers who want a Swiss Ronda quartz caliber in a format more unusual than a standard three-hand

How It Compares

vs. other Specht & Söhne models: The SP0028 is the only reversible case watch in the Specht & Söhne range at Jewelry Addicts. All other S&S models are standard fixed-case designs. The flip mechanism is the SP0028’s unique position within the brand.

vs. Farasute 5510B Swiss Quartz — The 5510B is a 37×27mm Swiss quartz rectangular at 6.7mm with sunburst Roman numeral dial. The SP0028 is a smaller 32.4×24mm Swiss Ronda quartz at 8.9–11mm with flip mechanism. Both are Swiss quartz rectangular dress watches — choose SP0028 for the reversible case feature; choose 5510B for the ultra-slim 6.7mm profile.

vs. Farasute 5321A-1 Art Deco — The 5321A-1 is Hangzhou hand-wound mechanical at 33mm rectangular with Art Deco pyramid markers. The SP0028 is Swiss Ronda quartz at 23.8mm with reversible case. Different scale, different mechanism, different complication.
