Vacheron Constantin Overseas Chronograph 49150 - Service & Polishing

Vacheron Constantin needs no introduction; each of its watches is a chapter in the history of Swiss watchmaking. The Overseas Chronograph Ref. 49150 is one of the most balanced expressions of contemporary sports-luxury design - a watch that combines technical excellence, functional durability and aesthetic harmony.

In our workshop in Thessaloniki, we carried out the complete service on this iconic chronograph, with respect to Vacheron Constantin's philosophy and fidelity to the manufacturer's strict specifications.

Disassembly & Cleaning

The first stage is the careful disassembly of the machine. Every component of the Caliber 1137, from the barrel and power transmission to the column wheel chronograph mechanism, is carefully removed and documented. The architecture of the movement, based on the Frédéric Piguet 1185, requires precision of movement and experience, especially when handling the fine levers and springs of the chronograph.

This is followed by deep cleaning with special watchmaking solutions to completely remove all traces of lubricants and dust. After drying, a thorough inspection under a microscope is performed; every gear, jewel and shaft is checked for wear or microcracks.

Reassembly & Lubrication

The reassembly starts with the barrier bridge followed by the installation of the transmission gears and the escape system. During the process, specialised lubricants are applied at precisely defined points - different for the high-speed parts, different for the friction parts of the chronograph.

The chronograph system is assembled step by step; the smooth operation of the column wheel and the pressure feeling of the pushers are checked. The mechanism undergoes adjustment and chronometric accuracy tests at multiple positions to ensure perfect oscillator balance.

Dial & Clock Assembly

After the operation check, the dial and the indicators are mounted. The silver guilloché dial with sub-dials and the large date window at position 12 require special attention to the alignment to ensure that everything works perfectly.

The engine is secured to the case and the distinctive 22K gold rotor with the embossed emblem of the Maltese cross is fitted - an element that makes the Caliber 1137 unique visually and mechanically.

Polishing & Finish Restoration

The last stage involves the restoration of the external appearance. The case and the bracelet are completely dismantled and cleaned. A combined satin and mirror finish is then applied to preserve the original Overseas character. Special care is taken to the unique "cross" design of the links, which restores the impressive light and shade variation without loss of material.

After polishing, a tightness check, final cleaning and visual inspection follows. The watch is assembled and subjected to operational and autonomy tests.

Result

The result is a Vacheron Constantin Overseas Chronograph 49150 that recovers its original glamour and functional perfection. A watch that combines the precision of the Caliber 1137 with the aesthetic excellence of Geneva; a chronograph ready to continue its journey with renewed energy and brilliance.

For us at The Watchmaker, every such project is a reminder that fine watchmaking is not only measured in complications, but in consistency, detail and respect for the work of the maker.
