Black was the safe launch color, and it still sold through. Blue is the second run at the Marine M1a, the dive watch that opened Timex Atelier last fall, and this colorway shows what the enamel dial can actually do. Pricing holds at $950 on the rubber strap and $1,050 on the steel bracelet, and both blue references are in stock at Timex US now.
Atelier is the Swiss-made sub-brand Timex built under creative director Giorgio Galli, and the Marine M1a was its first watch. Context counts here because this isn’t a color swap on a quartz diver. Inside a 41mm case sits a Swiss automatic movement, wrapped by a ceramic bezel, a double-curved sapphire crystal and 200 meters of water resistance.

Blue enamel and a ceramic bezel carry the color
Fired at high temperature, the enamel dial takes a deep, glossy finish that reads almost black at the edge of the light and turns properly blue across the face. Applied polished indices and silver-tone hands sit on top of it, filled with Swiss Luminova, so the layout stays clean and legible instead of busy. A diver lives or dies on that five-second glance underwater, and this dial passes it.
A unidirectional bezel turns around the dial with a blue ceramic insert, polished and engraved and matched to the enamel. Ceramic is the right call at this price. It shrugs off the scratches that mark up an aluminum insert, and the color won’t fade after a few summers of salt water and sun. In the dark, the Luminova plot at each hour and the filled hands do the work, with the bezel pip marking elapsed time.
A skeletonized 41mm case with a black IP core
Stainless steel forms the case, cut in a skeletonized architecture with a black IP-coated mid-case splitting the brushed outer sections. Dimensions run 41mm across, 48.11mm lug to lug and 13mm thick. Those numbers land in the range most wrists can pull off, and the dark middle layer breaks up the height, so the watch sits flatter visually than the spec sheet suggests.
Water resistance is 200 meters, which Timex rates for swimming, snorkeling, surfing and recreational scuba. A double-curved sapphire crystal covers the dial, and that curve pays off every time you roll your wrist under a light and the blue shifts. Flat glass would have been cheaper to make. It would also have flattened the one feature this colorway exists to show.
Catena SA100 automatic with hacking seconds
Inside is the Catena SA100, a Swiss automatic built by Catena S.A. with 29 jewels, a 28,800 vph beat rate and hacking seconds. Pull the crown and the second hand stops, so you can set the watch to the second. Timex quotes accuracy at ±15 seconds a day and a power reserve of about 38 hours for this reference. You can check the movement yourself through the display caseback, where the rotor and the jewel count sit in plain view.
Thirty-eight hours is an overnight reserve, not a long weekend one. Wear the watch on Friday and it’s still running Saturday morning, but leave it on the dresser until Monday and you’re winding and resetting. Daily wearers won’t notice. Rotators with a watch box full of alternatives will, and they should know that going in rather than after the first dead Monday.
Rubber at $950 and a bracelet that resizes without tools
An integrated blue NBR synthetic rubber strap carries the $950 version, textured, 20mm at the lugs, with a deployant clasp and a fit range of 150 to 205mm wrists. Rubber suits the job this watch is built for. It doesn’t soak up water, it rinses clean after a swim, and the blue carries the dial color down the wrist instead of stopping it at the case.

Stepping up to the bracelet adds $100 and swaps in a three-link stainless bracelet with self-adjustable links that resize without tools, plus quick-release spring bars for fast swaps. A tool-free resize sounds minor until you’re adjusting fit at an airport or on a boat, and then it’s the feature you tell people about. Between the two, the bracelet is also the version that covers a desk and a dinner without looking borrowed from a dive bag.

Blue is the one to get
Black proved the Marine M1a could sell at $950, and it left the enamel dial doing half its work in shadow. Blue finishes the idea. If you dive, swim or wear a watch hard through summer, take the rubber strap at $950 and put the saved $100 toward the next trip. If the watch also has to cover a desk and a dinner, the bracelet at $1,050 is the better buy, and its tool-free links make it the easier one to live with day to day.

Either way, this is the strongest argument yet that Atelier is a real watch line and not a one-off experiment. A Swiss automatic diver with an enamel dial, a ceramic bezel and a display caseback under $1,000 used to be a very short list. It just got a blue entry near the top of it, and the black version’s sellout says the line is not slowing down.
