Platform NH9131-14E Watch

The Watch

Citizen is a Japanese brand with over a century of history. It began by developing calculators and chronometers that revolutionized the world of athletics. Its innovative designs have long appealed to both men and women, and its timepieces are celebrated worldwide for their use of premium materials. Combining outstanding durability with reliable precision, this icon of modern watchmaking strikes the perfect balance between elegance and robustness. The NH9131-14E watch from the Platform Mechanical Open Heart collection reflects the brand's commitment to sophistication. Its round case, crafted from stainless steel, is built to resist wear and corrosion. Finished in grey with a polished surface, it measures 40 mm in diameter, 10.70 mm thick, and weighs 68 g. Sleek and refined, it features a flat mineral crystal that lets you admire every detail of the charming dial. These elements can be adjusted via the grey fluted crown of 5.50 mm, positioned at 2 o'clock. To let you appreciate every detail of the movement, the brand has fitted this watch with a screwed and transparent case back - which also contributes to its water resistance of 5 ATM.

The Dial

Simple and elegant, this stunning dial has everything you could want. Its black guilloché background creates a three-dimensional effect and ensures a clear, easy time reading. The minute track alternates between dashes and dots for a more dynamic feel. The dial features rose gold triangular indexes, with an Arabic numeral replacing the 12 o'clock marker. The dauphine hands and the lance seconds hand, both in rose gold, elegantly indicate the hours, minutes, and seconds. At 6 o'clock, a circular open heart reveals the intricate movement of the caliber and adds a dynamic touch to the dial. Finally, at 12 o'clock, you'll find the brand name followed by the model's movement type.

The Movement

At the heart of this timepiece beats an automatic movement - the Japanese Miyota 8229A caliber with a power reserve of over 40 hours. Reliable and robust, it features 21 jewels that minimize friction and drive the central hands with high precision, oscillating at a frequency of 21,600 vibrations per hour.

The Bracelet

Elegant and lightweight, the strap of this watch is crafted from calfskin leather. Featuring a black tone accentuated by tone-on-tone stitching, it complements any clean, understated look and fastens at the wrist with a silver-toned pin buckle.

Water Resistance

This model offers water resistance of 5 atmospheres, or 50 m. Designed to turn heads, it shines in any social setting. That said, its elegance doesn't compromise its resilience. You can wear it in the shower if needed, though the Ocarat team recommends leaving it safely on the edge of the sink to preserve its brilliance and integrity over time. For swimming or diving, we strongly advise against it - the risk of damage and costly repairs simply isn't worth it.
