The Otsuka Rotec Model 7.5 represents a unique blend of modern design and intricate engineering, featuring an innovative jumping hour module that echoes the sophistication often appreciated in high-end Japanese watchmaking.

Released as a limited edition, its unused condition enhances its desirability among collectors, especially given Otsuka Rotec's reputation for quality craftsmanship and limited production runs that often lead to increased value over time.

Priced at ¥745,000, this piece aligns with typical market values for luxury timepieces from Japan, where authenticity and condition significantly influence collector interest.

The watch's standout features, including its stainless steel build and sapphire crystal, establish it not just as a functional timepiece but also as a collectible statement piece for aficionados.
