Citizen is a renowned Japanese watchmaking brand whose creations captivate both men and women. It crafts elegant timepieces with great care, combining sophistication with durability. The prestigious Platform Mechanical Open Heart collection presents this stunning NH9131-73L watch. It features a round case in stainless steel with a beautiful grey tone enhanced by a polished finish. Solid and robust, it measures 40 mm in diameter, 10.70 mm thick, and weighs 125 g. A flat mineral crystal sits above the beautiful dial, letting you admire every stunning detail. The knurled crown at 2 o'clock allows for easy adjustment of the central functions. Stylish and distinctive, the screw-down case back features a transparent crystal for a fascinating view of the movement's inner workings. This case back ensures the watch a water resistance of 5 ATM.
The dial of this watch is full of exquisite details. Set against a guilloché blue background, it is delicately framed by a minute track for added precision. Inside, a set of triangular indexes in grey complement the beautiful dial design while marking the hours with precision. For a captivating touch, the 12 o'clock index is replaced by an Arabic numeral. The hours, minutes, and seconds are displayed by two dauphine hands and a lance seconds hand. An open heart complication at 6 o'clock lets you admire the intricate beauty of the movement. The brand's name and movement type are displayed at 12 o'clock.
This model is driven by an automatic movement that powers all its functions - specifically, the Japanese Miyota 8229 caliber. With an impressive power reserve of 40 hours, it features 21 jewels to minimize friction and beats at a frequency of 21,600 vph, ensuring smooth and precise hand movement.
Robust and elegant, the bracelet of this watch is crafted in stainless steel. Designed to adorn your wrist in style, it features 5 rows of polished and brushed links in a beautiful grey tone that perfectly complements the overall look of the watch. Light and streamlined, it is fitted with a silver deployant clasp.
This model offers water resistance to 5 atmospheres, or 50 m. Designed above all to be a stunning, head-turning piece, it wears its elegance without sacrificing durability. You can keep it on in the shower, though the Ocarat team recommends leaving it safely on the counter to preserve its brilliance and integrity over the long term. Swimming and scuba diving are not recommended - putting the watch at risk of damage and costly repairs.
