FAQ
What is the exact lug width of the Hamilton Khaki Navy H77351135?
The lug width of the H77351335 is 18 millimetres. This measurement refers to the distance between the two lugs on the case and is crucial for selecting a compatible strap. An 18mm strap will fit correctly into the lugs without play or forcing. Sizes such as 16mm or 20mm are not compatible.
Which type of strap is most recommended for the Hamilton Khaki Navy H77351135?
The ideal strap depends on intended use. For formal elegance, we recommend vegetable-tanned leather in brown or cognac tones, or alligator with vegetable tanning. For tactical or dynamic environments, a NATO strap in heavyweight cotton maintains military heritage. For water sports, butyl rubber or synthetic rubber offers superior grip on wet wrists.
How do you change the strap on the Hamilton Khaki Navy H77351135?
To change the strap, use a spring bar tool (two-pronged implement). Position one prong under the pin connecting the strap to the case lug, press gently to release the internal spring, then slide the strap outward. Repeat on the other side. When installing the new strap, ensure the pins insert into the 18mm lugs without excessive forcing.
Is an aftermarket 18mm strap compatible with the H77351135?
Yes, any strap manufactured for 18 millimetre lugs is compatible with the H77351135, regardless of manufacturer. However, always verify that the strap thickness is not excessive, as very thick straps could cause friction on the lug edges. Artisanal straps are typically calibrated with precision to this specification.
How long does a natural leather strap last on a watch like the H77351135?
A vegetable-tanned leather strap typically lasts between 2 and 5 years depending on use and care. Continuous exposure to moisture, perspiration and sunlight accelerates ageing. The patina that develops is natural and desirable, but if the strap shows structural cracks or lug failure, replacement is warranted. Regular maintenance with specialist creams can extend useful life.
