It’s always exciting when a brand releases a no-date tool watch. These watches often have busy dials, and, with the majority of brands, those dials feature dates that are afterthoughts, at best. Some simply cannot function without a date display, no matter how heinous its placement may be. The new Hamilton Khaki Navy Scuba watches are not for those people. Hamilton has just expanded two existing models with a healthy dose of green, introducing the Hamilton Khaki Navy Scuba Auto H82525160 and the Hamilton Khaki Navy Scuba Quartz H82241961. Both of these no-date models have been around for a few years (we went hands-on with the Auto in 2021). For the 43mm Auto, this new green variant is the fifth SKU, while the 37mm Quartz is one of seven SKUs. That said, its importance to any expansion is meaningful: When it comes to entry-level Swiss luxury, very few brands offer no-date divers, and almost none offer them at Hamilton’s sub-$1k prices.

The new Hamilton Khaki Navy Scuba Auto measures 43mm across and 13.85mm-thick with 22mm lugs. The case form is unremarkable, with crown guards around the screw-down crown (the Auto is rated to 300m water resistance), a sapphire crystal with AR coating, and a unidirectional dive bezel with a green ceramic bezel with a lumed pip. The dial features a deep green gradient with applied hour markers and an interior 24-hour scale; the seconds hand stands out for its red outline, and all the hands and markers get the Super-LumiNova treatment. The watch is completed with a stainless steel bracelet with a folding buckle closure. Through the watch, small, polished accents add a bit of character.

The 37mm Hamilton Khaki Navy Scuba Quartz measures just 10.77mm-thick with much smaller 18mm lugs. The case design is almost identical, though the bezel insert is a two-tone black and green aluminum; the watch has 100m water resistance, and it’s paired with a green textile NATO strap. The dial on the Quartz is a bit simpler, with a matte green that matches the green of the bezel insert and no applied ‘H’ logo. Otherwise, everything seems the same, except it appears that the lume here is Super-LumiNova C1 instead of the Auto’s apparent C3.

The Scuba Auto is powered by Hamilton’s H-10 movement, which is a branded ETA C07.611. This automatic movement is used throughout the Swatch Group family and is noted for its slower 21,600 vph beat rate that yields a higher 80-hour power reserve. While Hamilton isn’t entirely transparent about the movement in the Scuba Quartz, multiple sources confirm it’s an ETA F06.105. This is a gold quartz movement with three jewels, an end-of-life indicator, and up to 94-month battery life. In either case, you’re getting a robust Swiss movement that shouldn’t give you any headaches.

While it may be a safe color for the brand, it’s also one that allows consumers to feel like they have a colorful dial without being too loud about it. Further, green is about as crazy as Hamilton gets with color; these two new colorways will likely round out both model lines, barring some special editions. More importantly, you’ve now got three sizes of green Hamilton Khaki Navy Scubas (37mm, 40mm, and 43mm), two of which have no date. The Hamilton Khaki Navy Scuba Auto H82525160 is priced at $995 USD and the Hamilton Khaki Navy Scuba Quartz H82241961 is priced at $545 USD. Both models are available now from Hamilton and its authorized dealers. For more information, please visit the brand’s website.
