Its 14.45 mm case thickness is worth considering if you wear a watch under close-fitting cuffs. Hamilton’s US product page labels it part of the “Past collection,” so availability and price need to be checked in your market rather than assumed.
What the blue Intra-Matic Chrono is
H38416141 is the blue-dial version of Hamilton’s American Classic Intra-Matic Auto Chrono. Check the reference when comparing listings: the Intra-Matic Auto Chrono family includes other dial and strap variants, and a similar product name does not by itself confirm that a listing is this blue model. Hamilton lists the watch as an automatic chronograph with date and tachymeter functions, rather than a time-only watch. Hamilton’s product page identifies the reference and its specifications.
Design and historical connection
Hamilton says the modern Intra-Matic automatic chronograph draws inspiration from its 1968 Chronograph A. That is the manufacturer’s account of the design connection; it does not mean the modern watch shares the predecessor’s construction or specifications. Hamilton’s historical material describes the inspiration as the “famous panda dial” of the Chronograph A.
In its review of the blue model, Fratello Watches calls attention to the printed tachymeter, applied markers, small luminous details and 1960s styling. These details help explain the vintage-influenced look, but the available review material does not establish quantified independent tests of accuracy, comfort or chronograph performance.

Hamilton describes the H-31 as an automatic chronograph movement with an “extended 60-hour power reserve.” Treat that figure as the maker’s specification, not a guarantee of a particular result in every use condition. Likewise, the 10 bar (100 m) rating is a published water-resistance specification, not an independent assessment of a particular watch’s condition.

How the case dimensions may affect wear
The 40 mm diameter gives a useful starting point for comparison, but the 14.45 mm thickness is also important: a chronograph case of this height may sit more prominently beneath a cuff than a thinner watch. Wrist fit depends on the wearer and strap, and the available evidence does not establish a measured comfort result. If possible, assess the case on your wrist and with the kind of cuff you wear regularly.

Hamilton identifies its stainless-steel mesh strap as reference H6053841041. The watch’s listed 20 mm lug width makes other 20 mm straps a plausible option to investigate, but width alone does not confirm that a particular strap, end link or attachment will fit. Check the seller’s compatibility details or confirm with a watchmaker before ordering.
