The Navygraf Heritage YNAV25-ATP by Yema is a watch that stands out for its tonneau-shaped case crafted in 316L stainless steel. Made in France, this watch features a brushed matte and polished bright finish. With a thickness of 10.85 mm and a diameter of 39 mm, it delivers a compact yet robust design that captures the spirit of the 1960s. The screw-down case back contributes to an exceptional water resistance of 20 ATM, making this watch ideal for underwater activities.
The black dial of the Navygraf Heritage features a matte finish that contrasts beautifully with its luminescent hands and hour markers. The Arabic numerals on the bezel add a modern touch to this classic timepiece. The domed Hesalite crystal protects the dial while delivering exceptional clarity. The unidirectional rotating bezel in epoxy is enhanced by luminescent markers and a minute track, adding practical functionality. A discreetly integrated date window brings everyday utility while preserving the dial's overall aesthetic balance.
At the heart of this watch beats the Swiss automatic Sellita SW200 movement. This caliber delivers remarkable precision with a frequency of 28,800 vph (4 Hz) and a 38-hour power reserve. Engineered for lovers of reliable timepieces, this mechanism is a testament to Swiss watchmaking expertise. The rotor ensures smooth, consistent automatic winding, keeping the watch continuously powered.
The watch strap is available in two options: a 316L stainless steel version with a double-safety deployment clasp, and an alternative in rubber fitted with a pin buckle. Both options allow for a perfect fit on the wrist while accommodating each wearer's preference for classic or modern materials. The lug width measures 19 mm, ensuring a secure and comfortable fit, while the interplay of matte and polished elements enhances the overall aesthetics of the watch.
The Navygraf Heritage pushes the boundaries with a water resistance of 20 ATM, withstanding depths of up to 200 meters. This makes the watch perfect for adventurers and water sports enthusiasts, delivering superior performance even in the most demanding environments. The screw-down case back provides maximum protection against water intrusion, preserving the watch's internal movement.
