[Review] Casio F-91WS-7GH Watch: Classic Heritage with a White & Clear Twist

Hello, this is Lislab. When we think of watches, we are often drawn to the heavy presence of mechanical movements or bold metal cases. Yet, the timepieces we reach for most in our daily lives—those that add an effortless touch of wit to a casual outfit—are often surprisingly simple. Today, I’m looking at the Casio F-91WS-7GH , a modern take on the iconic F-91W that brings a fresh, contemporary edge with its clean white dial and semi-transparent clear resin strap. The original F-91W is a true legend, celebrated worldwide for its affordability, unmatched practicality, and featherweight fit. With a 7-year battery life and legendary durability that can handle almost anything, it earned a permanent place on wrists of all backgrounds. Let’s take a closer look at how this version builds on that heritage with a clear, refreshing feel.        ​

Hello, this is Lislab.

Today, I’m excited to share news about a special collaboration between Japan’s leading fashion lifestyle brand and a historic German footwear maker with over 250 years of heritage.

Sharing the pivotal milestone year of 1976, BEAMS and Birkenstock’s iconic 'Boston' clog have both maintained their legendary status in their respective fields for nearly half a century.

This post highlights the 'BEAMS x Birkenstock Boston' in a signature Crazy Pattern, released to celebrate both the founding of BEAMS and the birth of the Boston silhouette back in 1976.



01. Birkenstock

Built on the philosophy of "releasing the human body back to its natural state," Birkenstock is an authentic German footwear brand that has devoted over 250 years to studying foot health—often called the body's 'second heart.'

Utilizing anatomically engineered arch support and cork footbed technology, their shoes offer exceptional comfort that custom-molds to the wearer's foot shape over time.

Thanks to this uncompromising functionality and its retro outline, Birkenstock has secured a permanent spot as an essential item in classic Amekaji as well as modern daily style.

  • 250 Years of Uncompromising Craftsmanship

    • Ergonomic cork footbeds paired with meticulous construction distribute foot pressure evenly to deliver optimal fitting comfort.

  • The Iconic Silhouette: 'Boston'

    • First introduced in 1976, the Boston is Birkenstock's flagship clog, characterized by a smooth upper shell that gently hugs the instep and an adjustable strap buckle.

  • BEAMS’ Playful Signature Lineup

    • Collaborations with BEAMS infuse heritage footwear with BEAMS’ playful aesthetic and creative material mixing, creating highly collectible pieces each season.

What makes this collaboration so unique is that both BEAMS (founded in 1976) and Birkenstock’s iconic 'Boston' (introduced in 1976) are welcoming their 50th anniversary milestone together.

This edition features a 'Crazy Pattern' patchwork that three-dimensionally combines Birkenstock’s three signature suede shades: Taupe, Mink, and Mocha. By carefully piecing together different textures and suede tones, BEAMS has successfully infused its signature playful craft aesthetic into the timeless Boston silhouette.

The subtle asymmetrical color arrangement between the left and right shoes creates a fresh look with every step, striking a perfect balance between classic style and modern street flair.

Closing: BEAMS 50th x Birkenstock Boston


Rather than simply stamping two logos onto a product, this release thoughtfully reinterprets the shared 1976 heritage of BEAMS and Birkenstock using three distinct suede colors in a premium patchwork execution.

If you love the versatile styling of the Birkenstock Boston—whether paired with heavy workwear, classic tailored pieces, or relaxed casual looks—this collab edition offers a distinct character well worth adding to your radar.

Even for those who already own a classic pair of Bostons, the rare Taupe/Mink/Mocha Crazy Pattern and the historical 50th-anniversary context make this pair a valuable addition to any collection.

Thank you for reading this long journey.

Sincerely, Lislab
