EDITOR'S NOTE

Montblanc 1858 Collection continues to reinterpret the famous Minerva chronographs from the 1930s, with distinct designs and exceptional mechanics that traverse time.

The vintage style of the collection has been further enhanced by the introduction of bronze in 1858 Automatic Dual Time 44mm—a first for the Maison. Through this choice of metal, Montblanc combines traditional Swiss artisanal watchmaking with a genuine material from watchmaking history. For the first time in the watchmaking industry, bronze is coupled with steel and it results in a bi-color, bi-material combination that brings out the best of vintage design.

This piece, with its highly recognizable styling, features a traditional black dial, cathedral-shaped hands, and beige Super-LumiNova® Arabic numerals. The timepiece comes in a 44 mm satin-finish stainless steel case with a bronze bezel and crown.

Powered by the caliber MB 29.19, this automatic movement features a dual time complication entirely developed and assembled in-house with a home time indication and a day/night display.

The timepiece is completed with the authentic Montblanc logo from the 1930s on the dial and a brand new cognac-colored calfskin strap featuring traditional beige stitching just below the lugs and has been treated to give it an aged appearance—all in perfect keeping with the vintage theme.

HOW TO USE

• If you have not worn your automatic or manually wound watch for a prolonged period of time, wind it fully by turning the crown twenty times. Further details are specified in the respective service guide.
• In order to ensure the performance of your manually-wound mechanical watch, we advise you to wind the crown once a day, preferably at the same time
• Be careful not to force the crown once you feel resistance.
• Do not change the hour or date between 10 p.m. and 2 a.m., the period during which the date changes, as this may result in damage to the movement. Please refer to the service guide for further details.

CARE INSTRUCTIONS

• Do not expose your watch to temperatures higher than 60° Celsius (140° Fahrenheit) or lower than –10° Celsius (14° Fahrenheit). As your body and clothing will warm up the watch, its actual temperature will be different from the ambient temperature of your environment.
• In case of a shock to the watch, consult a Montblanc boutique or certified Montblanc retailer. Even if no scratches or dents are visible, the movement may be damaged.
• Do not wear other jewelry on the same wrist as your watch in order to preserve the patina of its surface and the integrity of the material.
• To preserve the pristine condition of your alligator, calfskin, satin, or rubber strap, avoid contact with humidity, salty water, soap, and cosmetic products.
• Do not treat your strap with wax, leather, or shoe polish, as chemicals may damage the leather, lining, or stitching. This may cause the strap to lose its original shine.
• Avoid prolonged exposure to high temperatures and direct sunlight to prevent the color from fading. Please note that strong perspiration may darken the leather. Diamonds, set on a bezel or crown, must be handled with care to maintain the lifetime of their brilliance.
• Avoid contact with chemical products such as fragrances and detergents, as these substances will tarnish precious stones. If your watch has been exposed to such products, clean it with lukewarm water and a soft toothbrush. Then, rinse it with fresh water and use a soft cloth to dry it or let it dry naturally.
• Never expose it to a direct heat source. Additionally, please be sure to check the stones regularly to ensure they are still securely set.
