This is the safest set of numbers on the site for an unknown wrist. 38mm across with a published 47mm lug-to-lug covers the broadest range of wrists of any watch here, and Hamilton publishes that figure, so you are checking it rather than hoping.
The 20mm lug width is the insurance. If it sits long or short on them, a 20mm strap in the right length fixes it for the price of lunch, and it will still be buyable in twenty years.
Sapphire and 100m mean it survives an owner who never thinks about either. The H-10 runs 80 hours, so it is still running on Monday after sitting on a dresser all weekend — which matters more on a gift than on a watch someone chose for themselves.
The cost is Hamilton's transparency: two years of warranty, and no US service price list, only a European one. You are buying a watch whose upkeep you cannot price before you buy it.
Mechanically identical to the Murph and usually cheaper, because it does not carry a film's name. 47mm lug-to-lug on a 38mm case is a genuinely versatile footprint.
