■ Buyer's comment
The SBDC207 is a perfect combination of alpinist history and the latest technology. When you actually pick it up, you will be drawn to the beauty of the teal blue dial. The deep colors that change their appearance depending on the way the light hits them have a charm that cannot be fully conveyed in photos.
Cal.6R55's 72-hour power reserve gives you great peace of mind that it will continue to work until Monday even if you take it off on the weekend. No matter how many times I watch the movement through the see-through back, I never get tired of it. You can fully enjoy the charm of mechanical watches.
The weight of approximately 147g is an exquisite balance that gives it a solid presence but also allows you to wear it for a long time without getting tired. Thanks to the diamond shield treatment, small scratches are less noticeable even when used outdoors.
The adduction ring with a simple compass is really convenient when used in the mountains. I feel that the design is both playful and practical, and is typical of an alpinist. Including the rarity of being a limited edition model, this is a must-see for alpinist fans. by Fujimuro
