The Heritage

The Hamilton Intra-Matic H38755751 is the contemporary evolution of an American watchmaking legend launched in the 1960s. This 42mm stainless steel case features a tonneau shape, clean dial, and minimalist aesthetics. It houses the automatic ETA 2892-A2 caliber with 42-hour power reserve, COSC-equivalent precision, and date function. The 316L stainless steel case is water-resistant to 50 meters. The 20mm lug width is proportionally calculated to maintain the design's slender profile and visual harmony of the iconic Intra-Matic family.

FAQ

What is the lug width of the Hamilton Intra-Matic H38755751?

The lug width of the Hamilton Intra-Matic H38755751 is 20 millimeters. This measurement is essential to ensure mechanical compatibility and preserve the aesthetic proportions of the tonneau case. To verify it, position a caliper between the two holes of the spring bar: the distance must be exactly 20mm.

Which strap should I choose for the Hamilton Intra-Matic H38755751?

The choice depends on daily use and desired aesthetics. Vegetable-tanned calf offers versatility and natural patina over time. Alligator ensures formal elegance. NATO or ballistic canvas maintain the model's military heritage. Rubber is the technical solution for high-humidity environments or maximum practicality.

How do I change the strap on the Hamilton Intra-Matic H38755751?

Changing the strap requires specific tools: a spring bar tool and steady hands. Position the watch on a soft surface, locate the lug holes on the sides, gently push the spring bar inward with the tool, remove the old strap, and insert the new one. If you prefer to avoid risk, trust a professional: Milano Straps can assist you.

Is an aftermarket strap truly compatible with the reference H38755751?

Yes, provided the lug width is exactly 20mm. A quality strap with the correct lug width fits perfectly without mechanical play. Always verify lug width specifications before purchasing. The 20mm straps from Milano Straps are tested to guarantee a perfect fit with the Intra-Matic.

How long does a leather strap last on a daily-wear watch?

A quality leather strap (calf, alligator, deer) typically lasts 2–4 years with moderate daily use. Durability depends on exposure to sweat, humidity, and maintenance: monthly cleaning with a soft, slightly dampened cloth significantly extends its lifespan. The patina that develops is part of its character, not a defect.
