Girard Perregaux Gyromatic Dress Watch

DESCRIPTION & SIGNIFICANCE

Here is an exceptional and beautifully preserved vintage Girard-Perregaux Gyromatic Automatic Dress Watch Reference B2002, dating precisely to the mid-1960s.

This specific example stands out as an incredibly honest mid-century Swiss timekeeper, representing a historic era of premium independent watch manufacturing. Powered by the highly regarded, in-house Girard-Perregaux Caliber 31 automatic movement, this piece offers a phenomenal blend of clean post-war geometry, a completely untouched original dial displaying a gorgeous sunburst texture with honest patina, and incredible vintage character.

While Girard-Perregaux was an elite manufacturer during this era, finding examples cased in 10K Gold Filled cases for the North American market that retain their original factory hardware—including a signed crown—makes this a highly desirable, "honest survivor" for vintage horological collectors.

CONDITION & COMPONENTS

• Overall Grade: Excellent / Unrestored (Dial) | Very Good / Sharp Geometry (Case)

• Originality: 100% original factory parts matching period-correct specifications. The hands, dial, case, signed crown, and mechanical components are fully verified for this mid-1960s production batch.

• Key Wear Notes: Honest micro-scratches from careful, historic wear are present across the gold-filled case. The winding crown is explicitly factory-signed with the correct "GP" logo, sitting low-profile with smooth, natural smoothing from decades of authentic use. The dial shows beautiful, light uniform aging and oxidation spreading evenly from the center, which serves as absolute proof against a poorly executed redial.

MOVEMENT & PERFORMANCE

• Caliber Engine: Bi-directional automatic winding, Girard-Perregaux Caliber 31 (Gyromatic) engine featuring 17 Jewels.

• Movement Design: Features GP's signature, proprietary Gyromatic roller freewheels instead of standard click-wheels to maximize winding efficiency. Developed as an esteemed collaborative design built upon an AS 1687 base plate.

• Service History: FULLY SERVICED

• Metrics: [Placeholder: timegrapher accuracy data, e.g., +15s/day / untested]

• Functionality: The movement features the crisp factory stampings "GIRARD-PERREGAUX GYROMATIC", "UNADJUSTED", and "SEVENTEEN 17 JEWELS" directly on the train bridges and rotor. These specific markings are period-correct U.S. customs import markers meant to navigate historic luxury tariffs.

DIAL & HANDS

• Variant & Condition: Correct original factory-born gold-tone dial featuring a magnificent sunburst texture. It displays applied gold-tone stylized Arabic numerals at the 12, 9, and 6 positions, paired with alternating faceted baton indices.

• Lume & Aging: Clean, non-luminous dress dial displaying an honest, uniform warmth and a gorgeous golden patina across the surface. Features the applied "GP" block logo and fully correct "Girard-Perregaux" signature centered below the 12 o'clock marker, "GYROMATIC" above the 6, and "SWISS"centered at the very bottom edge.

• UV Reaction: Non-luminous dial; no reaction under UV light.

• Hand Set: All hands are fully original and period-correct. The hour, minute, and sweeping center-seconds hands are elegant, polished gold baton variants that match the dial furniture perfectly.

CASE, BEZEL & CRYSTAL

• Dimensions: Approx. 34.0 mm w/o crown. 9.5 mm thickness, 18mm lug width

• Case & Lugs: 10K Gold Filled case architecture featuring classic, slightly downturned lugs that hug the wrist beautifully. Unlike thin gold plating, this thick gold-filled layer has mechanically bonded to a base core, preventing typical base-metal pitting or flaking.

• Components: The interior of the snap-on caseback houses the correct, matching factory stamps: the script monogram maker's mark, the reference code B2002, and the unique case production serial number F53787.

• Bezel & Crystal: Integrated smooth gold-filled fixed bezel. Fitted with a high-domed acrylic crystal that provides excellent visual depth to the textured dial beneath while remaining free of deep scratches.

STRAP & ACCESSORIES

• Hardware: Fitted with a matching gold-tone tang buckle.

• Fit & Wear: Paired with a New premium, vintage-style textured leather strap with stitching that perfectly accentuates the warm mid-century gold tones of the watch head.

COLLECTOR NOTES

• Provenance & Box/Papers: No box or papers.

• Vintage Disclaimer: This is a vintage, pre-owned timepiece with roughly 60 years of history. It is an honest, used object and is not cosmetically perfect. It displays character marks, micro-scratches, and component aging consistent with its era. Please perform due diligence by carefully examining all high-resolution photographs and macro images provided to ensure this piece fully meets your personal condition standards before making a purchase.
