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 39 jewel Girard-Perregaux Caliber 31.09 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: Automatic winding, top tier Girard-Perregaux Caliber 31.09 (Gyromatic) engine featuring 39 Jewels. (21,600 mph)

• 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 (with Zodiac, Doxa, Favre-Leba and Eberhard) built upon an AS 1687 base plate.

• Service History: FULLY SERVICED

• Metrics: Daily -18 sec per /day, Amplitude 286, Beat Error 0.0 ms

• 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. 11 mm thickness, 18mm lug width, 43 mm lug to lug

• 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

• 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.

A Note on Our Photography

To provide the most transparent representation possible, our watches are photographed using high-resolution macro photography.

We intentionally photograph our watches this way so you can evaluate each piece in greater detail than you typically could in person. Please keep in mind that macro images can make minor signs of wear appear significantly more prominent than they are at normal viewing distance.

• 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.
