The Citizen Collection PR1045-50W captures that quiet and beautiful moment when cherry blossom petals slowly flow on the surface of the water in a 28.5mm wide case. The gradation of cherry blossoms in full bloom on the white pearl dial and the open heart opening cut out in the shape of a flower bring back memories of spring in Japan every time you wear it on your wrist.
This model is limited to 1,200 pieces and is equipped with mechanical (self-winding + hand-winding) caliber 6628. The elegant color created by the pink gold case and the white of the white pearl oyster, and the open heart that allows you to see the gears in motion.Whether it's a gift or a treat for yourself, there's probably no better spring item than this.

■ With the motif of cherry blossoms flowing on the water surface - a scene created by white pearl shell x gradation
The dial of PR1045-50W is made of white pearl oyster. The beauty of natural materials that change their appearance depending on how the light hits them makes the gradation of cherry blossoms even more profound. The whiteness of the white pearl oyster reminds us of the surface of water, and the gradation of cherry blossoms in full bloom painted around it gives it a three-dimensional effect, creating a ``scene of cherry blossoms coloring the surface of the water.''
Furthermore, in the spaces between the flowers, there is a detailed depiction of gently flowing petals. The density of this painting-like dial is something that can't be described as specs; it's a special feeling when you see it in real life.
■ Cherry blossom-shaped open heart ─ The best part of mechanical technology through a special window
The most unique aspect of this model is the open heart opening. Only the PR1045-50W has an opening cut out in the shape of a cherry blossom flower instead of the usual circular shape. What you can see through the window is the sophisticated Caliber 6628 movement, which beats at a frequency of 28,800 vibrations per hour (8 vibrations). You can enjoy the mechanical beauty of the interlocking movement of gears and springs in the form of cherry blossoms.
Even for those who are experiencing the fun of mechanical watches for the first time, the fun of being able to see the movement through the see-through window should be exceptional. You can also see the rotation of the rotor that automatically charges the battery according to the movement of your arm.
■ Caliber 6628──Bringing the taste of mechanical technology to everyday life
It is equipped with Caliber 6628. It is a self-winding (hand-wound) mechanical movement with 21 jewels and a frequency of 28,800 vibrations/hour. The accuracy is typical of a mechanical type, with an average daily difference of -20 to +40 seconds under static conditions. Duration is approximately 40 hours at maximum winding. The rotor automatically winds when worn every day, making it suitable for everyday use.
Mechanical watches are the fundamental type of watches that do not use batteries. In today's world, people choose mechanical models because they value their "movement" and "presence." PR1045-50W encapsulates its value in the beauty of a cherry blossom scene.
■ Pink gold case x spherical sapphire glass - high-quality finish
The stainless steel case is plated with pink gold color. The warm gold that harmonizes with the soft hue of the cherry blossoms elevates it as a dress watch. The glass is made of spherical sapphire glass, which is scratch resistant and highly visible. It is water resistant to 5 ATM, so you can use it safely in everyday water environments.
The case size is 28.5mm wide and 10.3mm thick—the perfect size to fit comfortably on a woman's wrist. Weighing approximately 66g, the moderate weight of a mechanical watch gives it a strong presence on your wrist. You can experience the quality made in Japan with this one piece.

■ Buyer's comment
Citizen Collection's mechanical limited model is a series that is in high demand as a gift, but this cherry blossom version always makes me feel like it has a finish that I have never seen before. The idea of an open heart cut out in the shape of a cherry blossom is really interesting, and when you hold it in your hands, you can't help but think, ``Wow, that was a great idea.'' The combination of the water surface of the white pearl oyster and the gradation of the cherry blossoms is delicate, and at 73,700 yen, the quality of this design is sure to impress. We can confidently recommend this as a spring gift or souvenir.
