■ What is Happy Collection? A limited series that makes every day a little happier.
Seiko Rukia's ``Happy Collection'' is a limited series that gains popularity every year, with stories and colors based on a specific theme incorporated into the watches. It is created with the aim of being a presence that will accompany the wearer's daily life and bring out positive feelings.
This year's theme is "Warm Moments." The full-around dial has a heart motif, and a four-leaf clover and ruby are placed at the 7 o'clock position. The design incorporates the wish that every moment is a precious moment spent with someone. The rarity of only 600 pieces in Japan also adds to the joy of owning it.
■ Platinum Diamond Shield Coating ─ A combination of high-quality luster and durability
The stainless steel case has a platinum diamond shield coating. This surface treatment is highly resistant to scratches and abrasion, while maintaining a beautiful platinum-like luster for a long time. The practical strength required of a watch for everyday use is combined with a beautiful appearance.
In combination with sapphire glass (super clear coating), the visibility of the dial is ensured. The case size is approximately 36.32 x 27.7 x 7.73 mm, making it an exquisite size that fits neatly on your wrist.
■ Comfortex - The secret of a bracelet that fits your wrist well
HEE002J is equipped with a bracelet that uses Rukia's proprietary "Comfortex" technology. This structure, which is designed to follow the movements of your arm, provides a comfortable fit to your wrist from the moment you put it on, and has the practical advantage of being less tiring even when worn for long periods of time.
In addition, the length of the band can be finely adjusted with a snug fit. It is designed to make it easier to find the "just right size". Even if you choose it as a gift, the nice thing about it is that the recipient can start using it without stress.
■ 1B32 solar radio wave correction ── almost maintenance-free peace of mind
Powered by solar radio correction using caliber 1B32. Since it is charged by light, there is no need to change batteries during normal use. The battery lasts about 6 months when fully charged and about 1.5 years when using power save, which is a level that can be used safely on a daily basis.
The radio wave correction function supports standard radio waves in Japan, China, America, and Germany, and automatically corrects the time to the correct time. The fully automatic calendar is compatible until December 31, 2099, and automatically corrects for leap year date discrepancies. It also has an automatic hand position correction function and a time difference correction function, so you can take it with you when traveling abroad.

■ Buyer's comment
The Happy Collection is a series that I look forward to every year, and I especially like this year's "Warm Moments." The combination of the heart at 7 o'clock and the four color bars is not too overpowering, but it has its own personality. The clean finish of the white dial and platinum diamond shield will look great in the office or in your private life. Comfortex bracelets are so comfortable that once you put them on, you can't go back, and when you give them as a gift, people often say they are ``comfortable to wear.'' For 79,200 yen, radio-controlled solar, sapphire glass, limited edition of 600 pieces—this is definitely a good choice for cost performance.
