2. About the Watch

This custom Seiko mod features a rose gold-tone Nautilus-style case paired with a deep green horizontally textured dial and an open-heart window that reveals the balance wheel in motion. The combination of rose gold and emerald green, completed by a matching green leather strap, delivers a striking luxury-inspired presence on the wrist.

The build appears to use a 40–41mm case with an automatic Seiko open-heart movement such as the NH38/NH39 series, which are commonly used for Nautilus open-heart mods and offer reliable, hackable timekeeping with modern efficiency.
