Watch Description
To mark our company’s 55th anniversary, we are presenting the 910 Anniversary – limited to just 300 pieces and boasting a special technical feature. For in addition to a stopwatch, it also features a split-seconds mechanism for recording intermediate times. This split-seconds hand moves in sync with the second stopwatch hand until the push-piece is pressed at 8 o’clock. The split-seconds hand then remains in the ‘off’ position to allow you to read the intermediate time. On pressing the push-piece again, the split-seconds hand catches up with the second stopwatch hand and continues to move in sync with it.
The historical value of an additional feature adds to its appeal. The 910 Anniversary features a column wheel chronograph that stops the time. Timepieces constructed in this way are something of a rarity these days. They are regarded as technically demanding and as an expression of traditional watchmaking, since the column wheel control mechanism has been a key component in traditional chronographs since the mid 1900s.
While production is extremely complex, the utmost care and precision is required in assembly. Since the column wheel controls the start, stop and reset functions, it is subject to high levels of stress. The highest possible resistance to wear and tear is required in order to make full use of the benefits, for example an easy-to-operate push-piece. The workings of the perfectly synchronised mechanism can be admired through the transparent sapphire crystal back, which provides great aesthetic appeal.
Thanks to the vintage-look dial and attached appliqué, the chronograph also has a particularly high-quality and exquisite feel. To commemorate the 55th anniversary, the limited-edition number and the years ‘1961–2016’ are engraved on the case back.

# Sinn 910 Anniversary Split-Seconds LE-300 Review by A.I. WatchMetrics
## Watch Summary
The Sinn 910 Anniversary Split-Seconds LE-300 is a refined limited-edition split-seconds chronograph celebrating the brand's legacy, housed in a 41mm bead-blasted stainless steel case with a galvanic silver dial featuring black subdials, powered by a modified Sellita SW281-1 automatic movement with Dubois-Dépraz 2022 module and 42-hour power reserve, ideal for collectors and professionals seeking precise timing functionality in an elegant yet robust tool watch design.
## Overall Watch Rating: 8.9/10.0
**Movement Metric (9.7/10.0)** - The Sellita SW281-1 enhanced by Dubois-Dépraz split-seconds module offers exceptional complexity and reliability, on par with modified ETA 7750s in premium independent chronographs.
**Material Metric (9.6/10.0)** - Bead-blasted stainless steel paired with double AR-coated sapphire delivers premium durability and clarity, rivaling higher-end Sinn tool watches like the U50.
**Cohesiveness Metric (9.6/10.0)** - The design elements harmonize perfectly around the split-seconds theme, creating a unified collector piece akin to limited-edition IWC pilots.
**Complications Metric (9.4/10.0)** - The split-seconds chronograph function provides advanced timing precision, comparable to Greubel Forsey's more accessible siblings in utility.
**Dials & Design Metric (9.4/10.0)** - The silver dial with rhodium accents and balanced subdials achieves outstanding legibility and elegance, benchmarking against Nomos Glashütte's minimalist mastery.
**Versatility Metric (8.9/10.0)** - Suitable from boardroom to trackside, it matches the adaptability of Omega Speedmasters without dive-specific limitations.
**Functions Metric (8.7/10.0)** - Core timekeeping plus split chrono and date deliver robust utility, similar to Breitling chronos at this level.
**History & Innovation Metric (8.0/10.0)** - Sinn's 60+ years of aviation heritage and tech like dehumidification shine, though this model's split module builds on established precedents like Zenith El Primero evolutions.
**Rarity Metric (7.8/10.0)** - Limited to 300 pieces at this price point, it outshines mass-produced luxury chronos like Tag Heuer Carreras in exclusivity.
**Brand Metric (7.4/10.0)** - Sinn holds strong as a high-premium German specialist, akin to Oris in enthusiast appeal but with superior tool-watch credentials.
## Total Performance Score (TPS): 9.9
## WM Collector Grade: A+
## Performance Insights: Exceptional strengths in movement, complications, and materials make this a technical standout, with solid versatility and rarity offsetting moderate brand prestige for outstanding value versus its $7,200 implied price.
## TPS Interpretation: Superior Value: The watch punches far above its price with split-seconds sophistication and build quality typically reserved for twice the cost.
