The Caliber 7B72 (equipped with an electronic crown) features a high-quality solar radio clock. By adding a step to the case lugs, the contrast of light and shadow is emphasized, resulting in a sharp impression. The abbreviated characters are made from separate metal parts, enhancing the texture of the indices. The shape of the hands has also been revised, and with the addition of LumiBright, visibility at night has improved.
The sapphire glass is treated with a super clear coating, which reduces light reflection and enhances dial visibility, while the surface's anti-fouling film makes it less prone to dirt. With the electronic crown, adjusting for time differences becomes easier, and by receiving standard radio waves from six stations in five regions (Japan, China, the USA, Germany, the UK), the specifications have also improved.
With JIS Class 1 magnetic resistance, usability has been enhanced. Starting September 2, 2024, the manufacturer's suggested retail price will be revised. There may be products with tags showing the old price mixed in, so we appreciate your understanding.
