The brushing direction follows the NH72 movement’s bridge angles, creating visual coherence between the dial surface and the exposed mechanics beneath. We use C3 Super-LumiNova applied at 150 microns for over 8 hours of glow — each dial and hand set is individually checked for lume consistency before assembly. The case features deliberate brush-to-polish transitions: brushed tops, polished sides, mirroring the finishing language of high-end integrated-bracelet sports watches.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv itemscope itemtype=\"https:\/\/schema.org\/FAQPage\"\u003e\n\u003cdiv itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\"\u003e\n\u003ch3 itemprop=\"name\"\u003eCan I swap the dial or hands on this watch?\u003c\/h3\u003e\n\u003cdiv itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\"\u003e\u003cp itemprop=\"text\"\u003eYes.
