The MM300 is a slightly unusual watch because it is monoblock (without a case back) – meaning that the movement is encased from the dial side – ensuring great protection and the 300m water-resistance.
The MM300 is, as they say, a ‘serious watch for serious sports’ and at a serious price. This Steeldive interpretation, while remaining true to the spirit of the original MM300, is offered with a rather more ‘frivolous’ price tag. The Steeldive MM300, a watch for those who don’t take sports too seriously. Remember: sometimes coming second is better than coming first because you’re not a show off. Or a drugs cheat.
