Oris Big Crown Calibre 113vsHamilton Khaki Aviation Pilot Pioneer Mechanical Chrono

The Oris Big Crown Calibre 113 is noted for its distinctive mint green and rose pink dial, a 43mm stainless steel case, and an in-house hand-wound movement offering a 10-day power reserve. It includes a business calendar complication, day, date, and a non-linear power reserve indicator, with excellent readability provided by Super-LumiNova. One reviewer found the bold dial color potentially clashes with a business context and wished for a smaller case size. The Oris Big Crown Calibre 113 is priced at CHF 6,350 / €6,350 and includes a five-year warranty. Overall, reviewers highlight the Oris Big Crown Calibre 113's unique dial and extensive complications as its primary draw.

Owners and reviewers widely praise the Hamilton Khaki Aviation Pilot Pioneer Mechanical Chrono for its authentic military design, attractive dial execution, and intriguing asymmetrical case, with many appreciating its utilitarian feel and vintage vibe. The hand-wound H-51-Si movement, offering a 60-hour power reserve and accuracy around +5 to +7 seconds per day, is also noted positively, as is the satisfying feel of manual winding. Some owners find the 36mm case size light and versatile, while others note it wears larger than its dimensions suggest. However, several sources point to the mineral crystal as a drawback compared to sapphire, and the lume is generally described as weak. The included strap is frequently criticized for being too long and uncomfortable, with many preferring it on a NATO strap. On balance, owners and reviewers rate the Hamilton Khaki Aviation Pilot Pioneer Mechanical Chrono highly for its compelling vintage military aesthetic and solid value proposition.
