Montblanc Ecrire Le Temps Exhibition Tokyo Report

The Rolex Bubble Back, reference 1858, represents an early example of Rolex's self-winding waterproof wristwatches. This reference is part of the broader Bubble Back family, characterized by its distinctive domed case back designed to accommodate the thicker automatic movement of the era. It showcases Rolex's foundational efforts in developing robust and reliable automatic timepieces for everyday wear, laying groundwork for future Oyster Perpetual models.

This particular reference features an 18k white gold case, measuring 38mm in diameter. It is fitted with a sapphire crystal, protecting a silver dial. The watch is powered by an automatic movement, specifically the Boucheron 1858 caliber, offering a power reserve of 42 hours. The fixed bezel and leather strap complete the watch's classic presentation.

For collectors, the reference 1858 holds interest as an early and relatively rare iteration within the Bubble Back series, especially in white gold. Its larger case size for the period also makes it appealing to modern tastes. The presence of a date complication adds to its functionality, distinguishing it from simpler time-only Bubble Back models and highlighting Rolex's early integration of practical features.

The Montblanc 1858 Split Second Chronograph is a limited edition offering within the 1858 collection, distinguished by its complex split-second chronograph complication. This particular reference, limited to 100 pieces, features a unique burgundy dial, setting it apart from other models in the series and appealing to collectors seeking a more exclusive and visually distinct timepiece with advanced horological functions.

The watch is housed in a stainless steel case measuring 44mm in diameter and 15.2mm in thickness. It is fitted with a fixed 18k white gold fluted bezel. The dark burgundy dial, finished with a sunray pattern, complements the case materials. Protecting the dial is a sapphire crystal. The timepiece is powered by the hand-wound MB 16.31 calibre, which measures 38.4 x 8.13 mm, and offers a power reserve suitable for its intricate mechanical functions.

This reference appeals to collectors interested in high-complication chronographs and Montblanc's Minerva heritage. Its limited production run and specific dial color make it a notable variant within the 1858 collection, offering a blend of historical design cues and modern watchmaking. The large dimensions reflect its pocket watch-inspired movement architecture, a characteristic often appreciated by enthusiasts of traditional horology.

The Montblanc Star 4810 Automatic is a three-hand timepiece with an analog date display, positioned as an accessible offering within Montblanc's Star collection.

The watch features a 41.5mm stainless steel case, water-resistant to 30 meters. It is powered by a COSC-certified ETA 2892-A2 automatic caliber, modified to Montblanc's specifications.
