The Caliber 7B72 (equipped with electronic crown) features a high-quality solar radio clock. By adding steps to the case lugs, the contrast of light and shadow is emphasized, giving it a sharp impression. The abbreviated characters are made of separate metal parts, enhancing the texture of the indices. The shape of the hands has also been revised, and with the addition of LumiBrite, visibility, including at night, has improved.
The sapphire glass has been treated with a super clear coating. This reduces light reflection, improving dial visibility, and 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 been enhanced.
With JIS Class 1 magnetic resistance, usability has improved. From 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.
