Introducing the Supermarine 300m Date Bi-Colour, featuring a sleek profile case shape crafted in 904L stainless steel and 18ct rose gold.
The 18ct rose gold-capped, knurled-edged bezel showcases trapezoid indexes on the uni-directional brown aluminum insert, seamlessly transitioning onto the dial to form a naval-inspired crosshair that draws the eye to the striking brown gradient dial. Enhancing this design is the superior durability of the 904L steel case, an evolution from the previous 316L steel, paired with the clarity of applied indexes and Super-LumiNova® for exceptional visibility in low light. Completing the look is the elegant 18ct rose gold-capped screw-in crown.
Turning the case over reveals a case back engraved with a map of the world’s oceans, highlighting the purpose-driven design of this practical yet elegant sports watch.
Continuing our commitment to innovation, the Supermarine 300m Date Bi-Colour is fitted with our newly designed 904L steel bracelet. Featuring alternating polished and satin-finished infinity-shaped links, it offers exceptional fluidity and versatility.
For those seeking alternative styles, the Supermarine 300m Date Bi-Colour can also be paired with a quick-release brown leather strap with cream side stitch, adding its own distinctive character.

Very nicely made watch with a nice leather strap and watch. The dial in the teal color is great. I initially bought that color the turtle conservation but it grew on me. In an all black outfit, the teal is a nice accept while the hour marks and hands glow in the dark. I love it!
Amazing
Absolute seamless transaction! Fast communication, shipped promptly, will gladly purchase from again.
Great watch!!! Love the design and precision! Shipping was immediate!! Highly recommend Time Machine Plus
The watch is great; is everything I expected from watching numerous YouTube videos and reading reviews from trusted independent sites. More importantly is the service from Time Machine. This is my SECOND purchase from them and they didn’t disappoint; although the watch appeared on their site several weeks earlier it was not on the site because it was sold out. I called, an order was placed and at a great price. Consistency is appreciated! How many times have you dealt with a business and the first experience was positive and later not so much? This review is not intended to be or sound in any way hyperbolic. Too often if something or someone sounds too good to be true it turns out that way; not so here and that is the reason for the seeming rave; because they are the exception.
Great field watch, comfortable, and the green dial looks beautiful. The 38mm model is the perfect size.
All around a great purchasing experience. Fast shipping, everything arrived as expected, and great customer service.
