Richard Miller RICHARDMILLE excellent craftsmanship, perfect presentation of RM055 white ceramic, RM055 black ceramic. This model uses high light-transmitting glass, so that the large seconds are like walking inside the glass; the ultimate incredible craftsmanship can successfully achieve the quality of the original product, and the chamfers of the upper and lower ceramic shells are perfectly and smoothly presented. The arc effect is incredible for professionals. In addition, no matter how closely you look, the side liner and the upper and lower shells are completely integrated without gaps, and the craftsmanship is exquisite and rigorous. ✅Fully integrated with the original waterproof structural design (100% three-degree waterproof) ✅Always use the high-priced Japanese Citizen movement, which is accurate and durable. It will not use the Seiko movement that everyone is worried about, and the problem of pausing and jumping when the large seconds moves will not appear at all. ✅100% the original fluororubber and titanium head strap, even the English logo on the strap is magnified 200 times and there is no difference ✅Using the third-generation improved spring leaf folding buckle.
