Corgeut 42mm Cushion Case Hand-Wound Watch – Seagull ST3600/ST3601

Corgeut 42mm Cushion Case Hand-Wound Watch – Seagull ST3600/ST3601 | Sapphire Crystal | Sunburst Dial | Exhibition Caseback

The cushion case is one of the most distinctive silhouettes in watch design — a rounded square that softens the geometry of a rectangular case into something warmer and more organic on the wrist. It is a case shape with significant heritage in both Italian and Swiss watchmaking, associated with bold, character-driven timepieces that read differently from both round and rectangular designs. The Corgeut 42mm Cushion Case Hand-Wound Watch uses this silhouette to excellent effect — a deeply polished cushion case in 316L stainless steel housing a Seagull ST3600 or ST3601 hand-wound movement visible through a full exhibition caseback, protected by a sapphire crystal above, and presenting a sunburst radial dial in your choice of black, blue, green, or white. The sub-seconds register at 9 o’clock, the baton and Arabic numeral hour markers, and the vintage-toned hands give the dial a refined, tool-adjacent character that works equally well in casual and semi-formal contexts.

The Cushion Case — A Silhouette With Character

The cushion case shape of the Corgeut 42mm occupies a specific aesthetic register — it is more casual and expressive than a round case, more approachable than a rectangular case, and more visually interesting than either when the light catches the polished case facets. The bevelled case edges create reflective planes that shift as the wrist moves, giving the case a visual dynamism that a round case cannot achieve. At 42mm the cushion case wears differently from a 42mm round — the visual mass is distributed differently, and the watch reads as slightly smaller in presence despite the equivalent stated diameter. For buyers who find most watches either too conventional (round) or too formal (rectangular), the cushion case is the correct alternative.

Specifications

Colour Variants — Choosing Your Dial

Black dial — matte or lightly textured black surface with vintage cream/gold Arabic numerals and hands. The cream lume compound reads as warm and aged in daylight, glowing in low light. Paired with a black suede strap — the most classic and versatile combination in the range.

Blue dial — deep steel blue sunburst with white numerals and white hands. The radial sunburst finish shifts between navy and cerulean as the wrist angle changes. Paired with a blue suede strap for a colour-matched, intentional look.

Green dial — army green sunburst with cream/gold numerals and gold-toned hands. The combination of deep green and warm gold reads as considered and collector-aware — the same colour philosophy that has made green-and-gold one of the most discussed dial combinations in the affordable automatic market. Paired with a brown suede strap that complements the warm dial tones.

White dial (no luminous) — clean white surface with black Arabic numerals and black baton markers. Maximum daytime contrast, no lume compound applied. The simplest and most legible of the four variants in natural light. Paired with a brown suede strap.

The Sunburst Dial — Radial Light Interaction

Each coloured dial on the Corgeut cushion case watch uses a sunburst finishing technique — the dial surface is machined with fine radial lines that emanate outward from a central point, creating directional light reflection. Unlike a plain flat dial, a sunburst surface changes apparent shade and depth continuously as the wrist moves through different lighting angles. The blue dial shifts between deep and bright; the green dial shifts between olive and vivid army green; the black dial shifts between near-matte and a subtle sheen. This is the detail that makes these dials photograph well and reward daily wear — a sunburst dial is never the same twice.

Movement Note — ST3600 vs ST3601

Both the ST3600 and ST3601 are genuine Seagull hand-wound calibers with exhibition casebacks that display the full movement architecture including blued screws, striped bridge finishing, and the balance wheel. The specific variant shipped cannot be selected and is assigned at random from available stock. Both deliver equivalent hand-wound performance and visual quality through the caseback. The specific caliber received is noted in the shipping information.

How the Cushion Case Corgeut Compares in the Range

The Corgeut cushion case hand-wound watch is the most design-distinctive model in the Corgeut range — the cushion case silhouette and sunburst dial combination do not appear in any other Corgeut model at JwlrAddicts. For the Corgeut Flieger hand-wound watch with the same ST3600/ST3601 movement in a round case, see the Corgeut 42mm Flieger Hand-Wound Watch. For buyers who want a hand-wound mechanical chronograph with a Seagull movement in the JwlrAddicts catalog, the Phylida ST19 Reverse Panda Chronograph uses the Seagull ST19 column-wheel movement.

Frequently Asked Questions

Which movement will I receive — ST3600 or ST3601? The movement is assigned at random from available stock. Both are genuine Seagull hand-wound calibers. The specific variant cannot be pre-selected or specified at order. Both perform equivalently and both feature exhibition casebacks showing the full movement architecture.

Does the white dial variant glow in the dark? No. The white dial carries no luminous compound. It is designed for daytime and well-lit environments where maximum contrast is provided by the black numerals on white. For a luminous option, choose black, blue, or green.

What is the water resistance? 50M / 5 ATM — suitable for rain, handwashing, and splash exposure. Not recommended for swimming or submersion.

Is the crystal sapphire? Yes — sapphire across all variants, providing Mohs 9 scratch resistance.

What does hand-wound mean in daily use? Wind the crown 20–30 turns clockwise each morning to fully charge the mainspring. The watch does not self-wind through wrist motion. The resistance you feel as you wind is the mainspring charging — when resistance increases noticeably, the watch is fully wound.

Can I change the strap? Yes. The 22mm lug width accepts any standard 22mm strap — additional leather, NATO, or rubber options fit without modification.
