Osaka Expo: An Encounter at a Cafe - The Story of an On-site Measurement Service
The story of this special G-SHOCK strap began at the end of September 2025, with an encounter with a customer from Tokyo who was visiting the Osaka Expo.
📍 From Namba to Honmachi - One Autumn Afternoon
That day, after meeting another client in Namba, I headed towards Honmachi. The meeting place was a cafe on the first floor of the hotel in Honmachi where the client was staying during his visit to the Expo.
A warm encounter - overcoming language barriers
Although our ability to communicate in Japanese was limited, their warmth and friendliness easily overcame the language barrier.Very bright and openSo I was able to naturally relax and enjoy the conversation.
⏰ 1.5 hours
Due to the unique shape of the G-SHOCK, accurate sizing was necessary. The customer mentioned that the original rubber strap was a little long for his wrist (this is unavoidable, as Casio makes G-SHOCKs compatible with a wide range of wrist sizes).
We spent over an hour and a half, longer than usual, considering various specifications and deciding on the final design. Strangely enough, that long time felt very short. It was a special time, with lively conversation and the opportunity to share our love for watches.

The Artisan's Impressions - The Moment I Thought "I Want One Too"
When I picked up the customer's G-SHOCK to measure it, I was impressed by the watch's appeal.At that point, I didn't have a strong desire to have one myself..
The shock of seeing the finished product
A few weeks later, when I saw the finished G-SHOCK with the crocodile leather strap, I was astonished.
"This is... a completely different watch."
The transformation was far beyond my imagination. It had a sense of luxury, presence, and refined beauty that I hadn't felt with the rubber strap. The combination of the tough G-SHOCK case design and the finest crocodile leather created a truly"A complete transformation"It was.
At that moment, I made a decision."I'm going to buy the same G-SHOCK and make a crocodile leather strap."As a craftsman, I have made many watch straps, but there are not many that I have come across that are so well made that I truly think, "I want this."
The joy of craftsmen
It is the greatest joy for a craftsman to see the watch strap leather he has made blend perfectly with the customer's watch. And when the finished product is so good that the craftsman wants one for himself, it is one of the happiest moments in his job.

Impressive feedback from customers
After delivering the finished product, we received some great feedback and photos from the customer.

This statement says it all: the toughness and casualness of G-SHOCK remain intact, but the use of the finest leather takes luxury to a whole new level.
