If the Moonwatch is purity, the Mark 4.5 is progression.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cspan\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003eThe 42mm stainless steel tonneau case, with hooded lugs and sweeping radial brushing, continues the muscular design language first explored with the Mark II. Cushion-shaped, solid, architectural. But beneath the 'hesalite' (Omega’s trade name for a type of acrylic crystal), the Mark 4.5 moves in a slightly different direction. The dial adopts the distinctive “TV-style” layout, squaring off the registers and tightening the visual balance while preserving the bold legibility Speedmasters are known for.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cspan\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003ePowering it is Omega’s automatic Caliber 1045, derived from Lemania’s celebrated chronograph architecture.
