An iconic watch designed for professional divers: the Seiko Marinemaster Professional SBBN025, nicknamed "Ninja Tuna" or “Darth Tuna”, is synonymous with robustness and innovation.
It has a robust monobloc titanium case coated in black PVD with a diameter of 49mm. The lug to lug is also 49mm, resulting in a relatively compact and comfortable watch, as it is water resistant to a depth of up to 1,000m.
This case format developed by the Seiko team in the 1970s was innovative, as it allowed, without the installation of a valve (adopted by many Swiss brands), the reduction of the entry of Helium gas through the use of “L” joints, a monoblock case and overlapping ratchets to hold the crystal.
This model is a contemporary reinterpretation of the SBBN011 from the late 1980s, while maintaining the robust and reliable 7C46 quartz caliber, adjectives that have been corroborated over the last few decades.
Pre-owned watch in excellent condition. Complete with box, manual, card, tags and extra black Nato strap, original Seiko, in addition to the original black silicone strap.
Another opportunity for those who want a professional diving watch that carries on the legacy of the century-old Japanese brand Seiko in technological innovation and the construction of true diving tools.
