The new Supermarine 300m and 300m Date models have been entirely redesigned and now feature a new, sleeker and slimmer profile case shape crafted in 904L steel to maximise robustness and comfort in unison.
This new symmetrical case silhouette includes both crown and bezel guards, ensuring practical operation whilst increasing durability and safety by preventing accidental adjustment or damage through shocks or knocks.
The anodised aluminium knurled edged bezel features trapezoid indexes which flow from the bezel onto the dial, forming a naval inspired cross-hair, drawing the eye to the centre of the striking gradient dial. This is combined with improved durability, the clarity of applied indexes and the use of Super-LumiNova® for visibility in low light conditions.
An entirely new 904L steel bracelet has been developed for the Supermarine range offering exceptional fluidity and quality with an undulating shape which is well suited to all wrist sizes. Infinity shaped links alternate in a polished and satin finish. The watch is also available with a new military influenced chevron performance rubber strap or a vintage brown leather lifestyle strap with top stitching.
The case back is engraved with a map of the world’s oceans, emphasising the intent of the this practical elegant sports watch.

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.
