Review Montblanc Automatic Date 0 Oxygen The 8000 1858 130984 Watch

The Montblanc 1858 Automatic Date 0 Oxygen The 8000 (Ref. 130984) features a 41mm diameter and an 11.3mm thickness—dimensions that strike a perfect balance between a sporty aesthetic and everyday wearing comfort. Crafted from stainless steel and featuring an "Oxygen-Zero" design, the watch prevents fogging caused by temperature fluctuations at high altitudes and inhibits movement oxidation, thereby extending the timepiece's lifespan. The bezel is made of monobloc ceramic with a refined, lustrous finish; under the light, it reflects a soft, warm grey-black sheen that echoes the deep grey tones of the dial.

The dial features an "Ice Rock Grey" finish with a shaded effect and intricate texturing that mimics the look of glacial ice. The rhodium-coated Arabic numerals and sword-shaped hands are treated with a luminescent coating; the glow is practical rather than ostentatious, ensuring nighttime legibility while preserving the watch's vintage instrument aesthetic. The dial layout is clean and uncluttered, featuring only a date window at the 3 o'clock position. The typography is perfectly proportioned, maintaining the overall balance of the design. A subtle railway-style minute track encircles the dial, further enhancing its vintage appeal.

Turning the watch over reveals a distinctive detail: the case back is engraved with a motif paying tribute to the spirit of mountain exploration. Although it features a solid case back design, the engraving is intricate and three-dimensional, symbolizing the "spirit of exploration" that defines the 1858 collection.

The watch is powered by the MB 24.17 automatic movement, which operates at a frequency of 28,800 vibrations per hour and contains 26 jewels to minimize friction and ensure longevity. It offers a 38-hour power reserve—sufficient for a daily-wear timepiece. The watch has passed Montblanc’s proprietary "500-Hour Laboratory Test." This certification is more rigorous than the COSC (Swiss Official Chronometer Testing Institute) standard, encompassing not only timekeeping precision but also comprehensive testing for water resistance, shock resistance, magnetic field resistance, and temperature fluctuations. Achieving this certification demonstrates that the watch has undergone testing akin to "high-altitude training" before leaving the factory. It offers water resistance to 100 meters.

Audemars Piguet 38mm Royal Oak Chronograph

Like the new Royal Oak Perpetual Calendar launched last year, the Audemars Piguet 38mm Royal Oak Chronograph adopts a gradual rather than revolutionary improvement; essentially, it's still the same watch, just better. Audemars Piguet clearly understands that this watch must neither undermine previous successful designs nor fail to perfectly address the challenges it faces.

The challenge lies precisely in its nearly 40-year-old movement platform, which is now quite outdated. The 38mm Oak Chronograph has always used the 2385 movement, also known as the FP1185, now the Blancpain 1185 automatic chronograph movement. While its slim 5.5mm size remains impressive even today, its performance is truly lacking. 

The most significant change in the Audemars Piguet 38mm Oak Chronograph, model number 26450, compared to its predecessor, is the replacement of the old model with the new Audemars Piguet in-house 6401 automatic chronograph movement. This movement has a diameter of 27mm and a thickness of 5.7mm. Although its size is 0.8mm larger and 0.2mm thicker than the old 2385 movement, its performance and practicality improvements are truly revolutionary. Firstly, the frequency has increased from 21,600 vibrations per hour in the 2385 to 28,800 vibrations per hour. Secondly, the power reserve has increased from 40 hours to 50 hours, and an instantaneous date has been added. However, the most crucial highlight of this movement is its new vertical clutch control system.

This entirely new control method eliminates the previous pawl springs, operating only the first pawl and the second pawl with an integrated spring plate via the column wheel. This makes the chronograph pushers lighter to the touch, although not as light as the RD#5, but effectively reduces wear between the pawls and the column wheel. After pressing them, the feel was essentially the same as the 41mm Oak Chronograph, and compared to the older model, it's a complete blowout. Of course, this new structure has one drawback: it doesn't support flyback. But thinking about it, if it did support flyback, the 4401 movement of the 41mm Oak Chronograph would be unnecessary https://www.firstwatchclone.co/.

Besides the stunning new vertical clutch control, the upgrade to the escapement, which is of utmost importance to me, is a complete departure from the 2385. It not only features a free-sprung balance wheel and a transverse balance bridge, but also incorporates an in-line micro-adjustment balance wheel derived from the RD#3 and previously only found in Audemars Piguet's 7-series movements. And now, we can finally admire the movement's exquisite finishing through the transparent case back on the 38mm Oak Chronograph. While the exterior remains largely unchanged compared to the stunning movement, subtle adjustments have also been made to the details.

To accommodate the 6401 movement, the 12-hour and 30-minute chronograph subdials have been swapped. Secondly, while the three subdials are now the same size, the subdials at 3 and 9 o'clock have been slightly moved upwards, with their centers now crossing the center line of the dial. Thirdly, the date window is now perfectly positioned at the center of the 4 and 5 o'clock markers. Finally, Audemars Piguet has recalibrated the hour markers to match the new movement's 4 Hz frequency, and the two chronograph pushers are now further away from the crown. These seemingly minor details make this new 38mm Oak Chronograph appear more spacious and less crowded.
