How big is the green Hamilton Intra-Matic?
Diameter, thickness, and wrist fit
Hamilton lists a 40 mm case diameter and 14.45 mm thickness. Diameter gives a useful first fit reference, while the thickness is worth considering if you prefer a watch that sits low under a cuff. Wrist shape, strap adjustment, and personal preference affect how those dimensions wear. Hamilton’s cited page does not state lug-to-lug length or weight, so those figures cannot be confirmed here.

What strap size fits the H38416560?
Hamilton lists a 20 mm lug width and strap reference H6003841141, described as cow leather with a pin buckle and 18 mm buckle width. A replacement strap’s nominal 20 mm width is only a starting point: check the end shape and attachment method, and confirm whether you intend to reuse the original buckle. Hamilton’s product page does not establish that every third-party 20 mm strap will fit.
Movement, chronograph, and power reserve
Hamilton specifies an automatic H-31 chronograph movement and a 60-hour power reserve. The listed functions are chronograph timing, a date display, and a tachymeter scale. The reserve is a published specification; it should not be read as an independent test of how long an individual watch will run between full windings. The product page does not provide timing-accuracy results.

Water resistance: what 10 bar / 100 m tells you
Hamilton lists water resistance as 10 bar / 100 m and also lists a screw-down crown. That is the manufacturer’s rating, not independent confirmation of a particular watch’s condition or suitability for every water activity. The product page does not provide an independent test or a specific use recommendation, so do not treat the number alone as proof of dive-watch capability.
