Built for the modern man who values both heritage and performance, this 42mm stainless steel watch features a bold blue dial and a genuine cow leather strap, creating a look that transitions effortlessly from office to weekend adventures.

Key Features

• Swiss-Made Automatic Movement: Powered by the H-21 caliber, this self-winding movement eliminates the need for a battery. It harnesses the natural motion of your wrist to stay charged, and with a 60-hour power reserve, it remains accurate even during short periods of non-wear—perfect for those who rotate between multiple watches.
• 42mm Stainless Steel Case: The case strikes a balance between presence and comfort, offering a substantial yet wearable size that fits well on most wrist sizes. Its refined contours and clean lines reflect Hamilton’s attention to detail, making it appropriate for both formal occasions and everyday use.
• Vibrant Blue Dial: The deep blue analog dial provides excellent contrast and legibility, with clearly marked indices and hands. The color adds a modern edge to the classic design, making it stand out without being overly flashy.
• Sapphire Crystal: Renowned for its exceptional hardness, the sapphire crystal face resists scratches from everyday contact with keys, desks, and other hard surfaces. This ensures the dial remains clear and pristine over years of use.
• 100m Water Resistance: Rated for depths up to 100 meters (10 ATM), this watch is suitable for swimming, snorkeling, and surface water activities. It’s built to handle splashes, rain, and brief submersion, though it’s not intended for scuba diving or high-speed water sports.
• Genuine Cow Leather Strap: Crafted from durable cow leather, the strap offers a comfortable, breathable fit that molds to your wrist over time. Its classic appearance complements the watch’s design and develops a unique patina with age, enhancing its character.

Important Notes

This watch operates on a mechanical automatic movement and does not require a battery. However, if it’s not worn for several days, it may stop and need to be manually wound or placed on a watch winder to maintain accuracy. While it’s water-resistant to 100 meters, it should not be used for scuba diving, high-velocity water sports, or prolonged underwater exposure. To preserve performance, avoid exposing the watch to strong magnetic fields or extreme temperatures. The manufacturer’s warranty is available and can be requested directly through Hamilton’s customer service. The watch ships in original packaging measuring 6.1 x 5.4 x 0.2 inches and weighs just 3.53 ounces, making it lightweight and easy to store or transport. As a Swiss-made timepiece from a respected brand with a long history in watchmaking, the Jazzmaster Automatic reflects a commitment to craftsmanship, durability, and timeless design.
