■ “Shore” design concept
TSUYOSA's current lineup includes models themed around a variety of nature and places. This work, “Shore,” expresses the powerful dynamism of the seaside. The force of the waves, the feeling of life in the sea breeze - this design condenses those feelings into the red dial and gold and silver band.
The red on the dial is an exquisite color that is passionate yet not too flashy. The band, which is a mixture of gold and silver, brings out the red, and it feels strangely fitting when you put it on your arm. When you see the real thing, you will feel that it is ``better than the photo''.
■ Mechanical charm created by Cal.8210
The caliber 8210 installed in the NJ0234-58X is a mechanical movement that supports automatic and manual winding. With 21 jewels and a frequency of 21,600 vibrations per hour, it is a mechanical movement with high cost performance that Citizen is proud of. The power reserve of approximately 42 hours at maximum winding also gives you peace of mind from a practical standpoint.
The rotation of the rotor, visible through the see-through back, is the real thrill of mechanical watches. Every time you put it on, you can feel that it's "moving" - an experience that battery-operated products don't have, and it will enrich your everyday wear.
■ Diver's style with 120 click bezel
The unidirectional rotating bezel is a feature that allows you to manage your dive time when diving. The bezel is engraved with a fine pitch of 120 clicks, making it comfortable to operate, and is both practical and stylish. Even if you don't go underwater, the presence of this bezel will give your wrist an authentic look.
The sporty look that is TSUYOSA's design language and the diver's bezel go perfectly together. It has the ability to fit into any situation, whether it's running along the beach after work or outdoors on the weekend.
■ "Authentic feel" created by the weight of approximately 148g
Approximately 148g with full stainless steel + gold-plated case and band. It may feel a little heavy for those who prefer "lightness," but for those who like mechanical diver's style, this weight is the key to creating a "realistic feel." The balance is exquisite, conveying its presence to your arm without making it feel uncomfortable and heavy.
The big face with a case size of approximately 45.5 x 40 mm has high visibility and matches casual and sports styles better than suits. If you are looking for a watch with a strong presence, this sizing is a big attraction.
■ Sapphire glass + 10 ATM waterproof ability
The glass is made of sapphire glass, which prevents scratches and maintains its beautiful condition for a long time. Water resistance is 10 ATM, which is suitable for swimming and snorkeling. It is a full-fledged model that can be used even at the seaside, and is suitable for the "Shore" theme.
It also has a type of magnetic resistance, and is designed to allow you to use your mechanical watch with peace of mind in all kinds of everyday situations.
■ Available in 2 models including NJ0232-53X
TSUYOSA with the "Shore" theme has two models: NJ0234-58X (red) and NJ0232-53X (different color). Same concept and same movement, but different dial color and band expression. If you are having trouble choosing a color, please compare the two models side by side.

■ Buyer's comment
The coloring of TSUYOSA's mechanical designs is very aggressive, and I get excited every time I see a new one. This time's "Shore" theme of red and gold is particularly unique. At first I thought it was flashy, but when I put it on, it turned out to be surprisingly natural. When you see the rotor spinning through the see-through back, you'll be drawn into the mechanical swamp (lol). If you like the "authentic feel", including the weight of about 148g, this is a must-have item.
