Junpei Seki is a fashion improver who works extensively in Tokyo and Paris. He runs the select shops "PARKS Paris" and "keylime Tokyo," and is involved in planning and directing for domestic and international brands. He continues to communicate his unique perspective that connects fashion and lifestyle.


First, we'll bring you the latest fashion from inside "keylime Tokyo," where new items are on display!


Today, Seki's styling features new Keylime black denim pants with a wide silhouette, paired with Le Yucca's suede bit loafers. It's an elegant and sophisticated style that isn't too casual.


From the store, which is filled with new arrivals, we asked Tsuchiya to suggest some recommended items. "They're elegant, easy to coordinate, and all of them are incredibly cool," said Tsuchiya, already delighted before we even got to the theme of this article.

Learning from Seki-san – When choosing a watch, the key is the "view on your wrist."

Now, onto the main topic: today's theme is "wrist coordination." Seki will be introducing keylime's new watch, "VAGUE WATCH Co. for keylime Exclusive."


Born from Seki's desire to wear a watch that he could wear every day, amidst the current market offering everything from status-conscious luxury watches to rare vintage timepieces, this mechanical watch is a keylime original model filled with Seki's personal touches, created in collaboration with the Japanese brand VAGUE WATCH.

The watch is 34mm in size, and the dial features a bar index only at the 12 o'clock position, with a distinctive Keylime green color.
The case comes in two colors (steel and combination), and the set includes two bracelets: one metal and one leather (green) (includes a special tool and box). Furthermore, the reverse side of the leather bracelet can be chosen from two colors, beige and green, adding a playful touch.



Now, let's ask Seki-san to suggest some recommended pairings for Tsuchiya and Tashiro.

Tsuchiya | Embrace elegance with metal


Tsuchiya's watch features a steel case and metal bracelet, creating a dressy look for the wrist. While maintaining the elegant 34mm size, the subtle protrusion of the domed crystal adds a touch of presence.




Tsuchiya : The size is just perfect. Even at 34mm, it doesn't feel lacking. It's incredibly elegant.

The entire crew notices a change in the appearance of their hands.

Next, Tashiro proposes a style that adds a playful touch of color to a simple outfit, combining a gold case with a green leather strap. It can also add elegance and a relaxed feel to casual outfits like jeans.


Tashiro : Cool. So calming. This is nice.

Seki : For men, it's fun to deliberately incorporate color into casual outfits, and I think it would also be interesting to incorporate it into dinner or suit styles.


Furthermore, Seki introduced the two women to accessories that complement their watches. As Seki said, "Keylime's aesthetic is about being a 'refined adult' who doesn't get overshadowed by the watches," so they picked out a slender chain bracelet that would not be overshadowed by the watches and would create an elegant overall look.

For Tsuchiya, I chose a chain bracelet with understated silver accents and a touch of gold.

For Tashiro, we selected a 9K mixed chain that pairs well with the two-tone watch.

When choosing a watch, Seki says, "The key is to focus on the 'view' of your wrist that you see every day, rather than how it looks in the mirror," and the two agreed. The use of a chain bracelet adds a touch of adult sophistication and sexiness, giving off a mature aura.


Let's enjoy watches as a fashion statement!


As Seki says, "The fun of this watch is that even though three people are wearing the same model, they look so different." Why not enjoy using a watch as a fashion accessory? With the Christmas season upon us, it's perfect not only as a gift, but also as a "well done for the year" gift for yourself.
