This version of Hamilton's charming Intra-matic auto is a hybrid of two designs at a new size. By mixing the svelte lines of the dressier 38mm model with the coloration and attitude of the motorsport-fueled chronographs in a mid-size 40mm case, Hamilton has created a great every day watch. Just elegant enough to slip under the cuff at work, while bold enough and aggressive enough for weekend fun.

Fueled by a retro aesthetic, the Intra-matic Auto 40mm has gorgeous case lines with sharp lugs, and a gently domed sapphire crystal. Two-tone dials in blue/beige or beige/black mix applied markers and printed numerals for a classic look. Strong hands make reading the time easy no matter the angle, and a date at six keeps the dial symmetrical. Lume plots on the dial and hands give you an edge in the dark, and gorgeous leather straps make the watches ready to wear out of the box.

Inside of the Intra-Matic Auto, you’ll find Hamilton’s impressive H-10 Swiss-made automatic movement. With an impressive 80-hour power reserve, it also features an anti-magnetic Nivachron hairspring, 25-jewels, date, hacking seconds, and a frequency of 21,600bph. This is a reliable movement with a great power reserve.
