Ralf Tech WRB Automatic California Watch WRB 1007

The Watch

The watch is a stunning creation by Ralf Tech, embodying a classic, elegant aesthetic inspired by the 1930s. Designed in France, it stands out for its 316L stainless steel case, delivering unmatched toughness and corrosion resistance. The barrel-shaped case, with its smooth, harmonious curves, measures 39 mm in diameter - the perfect size for a wrist presence that's confident without being imposing. The alternating polished and satin finish gives this piece captivating visual depth and a play of textures. Featuring a unidirectional rotating aluminum bezel, the watch delivers the functionality and aesthetic of a sophisticated diving tool. The screw-down caseback ensures both enhanced water resistance and added structural solidity. This watch, a limited edition of 100 pieces, is a vibrant tribute to traditional timepieces - blending bold functionality with timeless style.

The Dial

The matte black dial delivers exceptional legibility, enhanced by a unique blend of Roman and Arabic numerals in gold that nod to classic 1930s watchmaking. These markers, treated with SuperLuminova "Old Radium", glow brilliantly in the dark for flawless readability in any lighting condition. The hands, also luminescent, sweep elegantly across the dial - precise and visible at all times. A tribute to the tradition known as "California", this watch features a dial once called the "error proof radium dial", prized for its unmatched legibility by US Air Force and US Navy pilots. The dial is protected by a domed sapphire crystal with anti-reflective coating, preserving every detail of its nostalgic elegance and modern innovation.

The Movement

At the heart of this timepiece beats a Japanese automatic movement, caliber RTA003, reflecting the highest standards of precision and durability. With a 40-hour power reserve, the watch offers comfortable autonomy - keeping accurate time all day and beyond without frequent winding. The movement is fitted with a rotor, a testament to horological ingenuity through the fluid, continuous motion that defines modern mechanical movements.

The Strap

The watch comes with two straps - one in hand-stitched black calfskin leather and one in black "tropic" rubber - both premium materials that bring a look that's equally refined and built to last. With a 22 mm lug width and a steel pin buckle, the straps deliver a secure, comfortable fit for all-day wear.

Water Resistance

With water resistance to 20 ATM, this watch is built to handle the most demanding environments and intense water sports - from scuba diving and surfing to jet skiing. Its screw-down case and screw-down crown reinforce structural integrity, providing total water protection down to 200 meters.
