At the core of the Type 300 lies a robust Japan Automatic movement, featuring two hands, a date function, and a small seconds dial. This movement ensures precise timekeeping and reliability, echoing the dependable performance of the Spitfire itself. The stainless steel case, with its gunmetal grey finish, measures 42 mm in diameter and 13.6 mm in thickness, presenting a durable and stylish profile that is both striking and wearable.

The lug-to-lug measurement of 50 mm ensures a comfortable fit across a wide range of wrist sizes, making this watch not only a statement piece but also a practical choice for daily wear. The sapphire lens, enhanced with an anti-reflective coating, offers unparalleled clarity and resistance to scratches, ensuring the watch remains pristine and legible in all conditions.

Applied indexes with Swiss luminous material illuminate the dial, allowing for easy reading in low-light environments. This feature, coupled with the watch's aviation-inspired design, pays homage to the Spitfire's operational excellence during critical missions.

The solid stainless steel bracelet, complete with a solid fold-over buckle and safety lock, provides a secure and comfortable fit, ensuring the watch stays in place during any activity. Additionally, an extra leather strap is included, offering versatility and the opportunity to personalize the watch's appearance to suit different occasions or preferences.

With a water resistance rating of 5 ATM, the Type 300 is capable of withstanding splashes and brief immersions in water, making it suitable for everyday wear but not for swimming or diving activities. Weighing in at 160 grams, it has a substantial feel that reassures of its quality and durability.
