■ Happy Collection - Four-leaf clover that brings happiness

SSQW100 is a new item from the Happy Collection, with a four-leaf clover, a symbol of good luck, subtly sparkling at the 7 o'clock position. The vibrant Arabic numerals, inspired by balloons, are both easy to read and playful.

The long-selling model has been made of titanium, making it surprisingly light at approximately 34g. It's so comfortable that you'll forget you're even wearing it, and it'll brighten up your everyday life.

■ Beautiful brilliance of the white pearl dial

The dial is made of white pearl oyster and shows various expressions depending on the angle of light. The gentle shine that only natural materials can give will give your arms an elegant look.

The gold-colored indexes and hands highlight the shine of the white pearl oyster, creating an elegant atmosphere. The harmony with the lady gold color case is also beautiful.

■ Made of ultra-light titanium, weighing approximately 34g

The case and band are made of lightweight and durable titanium. Weighing only 34g, it's so comfortable you'll forget you're even wearing it. You won't get tired even if you wear it for a long time, making it perfect for everyday use.

Platinum diamond shield processing ensures scratch resistance and long-lasting beautiful shine. The lady gold color finish gives it a gorgeous and elegant impression.

■ Easy size adjustment with easy adjustment

The band uses the ``Easy Adjustment Type,'' which allows you to easily adjust the size without the need for tools. It's convenient because you can quickly respond to changes in your arm circumference due to the season or your physical condition.

The maximum arm circumference is approximately 18cm, and it is designed to fit even slender women's wrists.

■ Radio solar compatible with 4 areas around the world

It receives standard radio waves from four areas around the world: Japan, China, America, and Germany, and automatically adjusts the time. The radio wave correction function keeps accurate time at all times.

The solar charging function allows it to be charged using sunlight or indoor light, so there is no need to regularly replace batteries. It can last for about 6 months when fully charged and about 1.5 years when in power save mode, so you can use it with confidence.

■ Full auto calendar function

Fully automatic calendar function eliminates the hassle of date adjustment until December 31, 2099. It automatically detects leap years, which is very convenient.

It is also equipped with an automatic needle position correction function, which automatically returns the needle to its correct position even if it is misaligned due to an impact.

■ Sapphire glass is scratch resistant

The windshield is made of sapphire glass with a super clear coating. It combines high transparency and scratch-resistant hardness, allowing you to clearly see the beauty of the dial.

It suppresses light reflection and achieves excellent visibility, making it easy to see the time from any angle.

■ 10 ATM water resistant, safe for daily use

Reinforced waterproofing for daily life (10 ATM) allows you to use it with confidence not only when washing your hands or in the rain, but also when working with water. The great thing about it is that you can wear it without hesitation in all kinds of everyday situations.

■ Nickel allergy resistant specification

It is nickel allergy resistant, so even people with metal allergies can use it with confidence. The skin-friendly titanium material provides a comfortable fit.

■ Anti-magnetic performance for peace of mind

It has anti-magnetic properties, making it less susceptible to the effects of magnetism that comes into contact with smartphones, computers, and other devices in daily life. The functionality that suits modern lifestyles is attractive.

■ Comes with a smartphone strap

As a bonus, a smartphone strap is included. I love that you can enjoy coordinating it with a watch.

■ High quality made in Japan

This is a high quality watch made in Japan. The watchmaking technology that Seiko has cultivated over many years is condensed into this one watch. Please feel the world-class Japanese technology on your wrist.

■ Buyer's comment

The moment I picked up the SSQW100 for the first time, I was surprised at how light it was. Weighing about 34g, you'll almost forget you're wearing it, and it'll keep you comfortable all day long. The white pearl dial has a wonderful shine, and the expression changes every time you change the angle, so you'll never get tired of looking at it. The subtly sparkling four-leaf clover at the 7 o'clock position is cute and makes me feel happy every time I see it. The lady gold color case is elegant and easy to match with any fashion. It's radio-controlled and extremely practical, so you can use it every day with confidence. by Fujimuro
