Farasute 5510B Rectangle Swiss Quartz Watch — 6.7mm, 37×27mm, Sapphire, Art Deco

The Farasute 5510B is an ultra-slim Swiss quartz rectangular dress watch at 6.7mm total case thickness — the thinnest watch in the Farasute range. The 37mm × 27.2mm case creates a long, narrow proportional format. Sunburst dial with Roman numeral markers, sapphire crystal, 316L stainless steel case, head-layer cowhide leather strap with Italian lining, 3ATM water resistance. Available in salmon, silvery, brown and dark green.

Key Specifications

Variants — Four Dial Configurations

Salmon: Warm salmon dial on taupe leather — the most vintage and formally resonant configuration. Salmon on a rectangular Art Deco case is the specific combination associated with 1930s formal dress watches.

Silvery: Bright silver sunburst dial with sharp contrast markers — the most legible and formally neutral of the four. The sunburst creates directional shimmer under ambient light.

Brown: Rich chocolate-brown dial with matching leather strap — warm, cohesive and understated. The brown-on-brown creates the most casual-formal character of the four.

Dark green: Deep green sunburst dial on dark leather — a contemporary interpretation of the Art Deco rectangular format. Green dress watches are specifically collected and the 5510B in dark green is among the thinnest available.

6.7mm — The Thinnest Farasute

At 6.7mm the 5510B is the thinnest watch in the entire Farasute range by a significant margin:

• Farasute 5510B: 6.7mm (Swiss quartz, rectangular)
• Farasute 5336B: 7.95mm (Seagull hand-wound, regulator)
• Farasute XK-009A: 8.3mm (Hangzhou hand-wound, round)
• Farasute 5506B: 8.2–8.6mm (Hangzhou hand-wound, round)
• Farasute Square Ultrathin: 8.9mm (Miyota 9019, square)

The 6.7mm profile is achievable because a Swiss quartz movement is significantly thinner than any mechanical movement. For buyers who specifically want the thinnest possible dress watch — one that creates absolutely no lift under a shirt cuff — the 5510B is the correct choice in the Farasute range.

Swiss Quartz Movement

The 5510B uses a “Swiss Original” quartz caliber — the movement is Swiss-manufactured quartz. The specific caliber designation is not named in the product documentation. Swiss quartz movements are produced by ETA, Ronda, ISA and several smaller Swiss manufacturers; the 5510B’s caliber is one of these. Swiss quartz provides ±15 seconds per month accuracy with battery life typically 2–3 years.

For buyers who want the highest mechanical complications, Swiss quartz is not the correct choice — see the Farasute mechanical range. For buyers who want maximum thinness, maximum formal dress character and no winding maintenance, Swiss quartz is the correct movement type for the 5510B’s purpose.

37mm × 27.2mm Proportions

The 5510B’s rectangular dimensions create a specific proportional character: 37mm long, only 27.2mm wide. This extreme elongation along the wrist axis — 1.36:1 length-to-width ratio — is consistent with the most formal vintage rectangular dress watches of the 1920s–40s, where narrow cases worn long-axis to the wrist were the norm for formal instruments.

On the wrist the 37mm length spans the width of most wrists while the 27.2mm width creates a narrow, refined visual footprint. The watch reads as smaller and more understated than a 38mm round watch despite similar lug-to-lug span.

Sunburst Dial with Swirl Pattern

The sunburst-textured dial creates radial light reflection — the pattern shifts between bright and slightly recessed areas depending on the light source angle. The “swirl-mark” detail refers to the circular buffing pattern on the sunburst surface, creating concentric light circles within the radial sunburst. Roman numeral markers are elongated — an Art Deco design convention where the tall, narrow numeral style suited the elongated rectangular case proportions.

Art Deco Inspiration

The 5510B’s design references 1920s–30s rectangular dress watch design throughout — the case proportions, the elongated Roman numerals, the sunburst dial and the fluted crown with cabochon accent are all elements from this period. In the Art Deco era rectangular watches were the prestige format for formal dress — the most famous rectangular designs from this period remain among the most valuable vintage watches. The 5510B interprets this aesthetic in contemporary materials at an accessible price.

Who Is the Farasute 5510B For?

The 5510B is built for:

• Ultra-slim buyers who want the thinnest possible dress watch — 6.7mm is the thinnest in the Farasute range and among the thinnest mechanical/quartz dress watches at this price
• Swiss quartz accuracy buyers who want low-maintenance timekeeping in a formal rectangular dress watch
• Art Deco rectangular format buyers who want the 1920s–30s proportions in a contemporary quality build
• Dark green rectangular dress watch buyers — the dark green sunburst on a 6.7mm rectangular case is a combination available at very few prices

How It Compares in the Farasute Range

vs. Farasute 5336B Regulator — The 5336B is 7.95mm at 39mm round with Seagull hand-wound mechanical. The 5510B is 6.7mm at 37×27mm rectangular with Swiss quartz. The 5510B is thinner; the 5336B has mechanical character. Choose by movement preference and case shape.

vs. Farasute 5321A-1 Art Deco — The 5321A-1 is 33mm rectangular at 10.5mm with Hangzhou hand-wound and pyramid markers. The 5510B is 27.2mm × 37mm at 6.7mm with Swiss quartz and Roman numerals. Significantly different proportions and movement type.

vs. Farasute 2260 Quartz — The 2260 is 36mm tonneau at 9.4mm with Seiko VH64 and day-date. The 5510B is 27.2×37mm rectangular at 6.7mm with Swiss quartz and no calendar. Choose 5510B for the slimmest profile; choose 2260 for day-date calendar.
