MODEL \/ REFERENCE:<\/span><\/b> Nivada Grenchen Chronomaster Aviator Sea Diver \u201cSpecial Logo\u201d, reference 0\/4076. <\/span>Inventory Code: MT-2602-14. <\/span> <\/span><\/p>\n

ZIFFERBLATT + ZEIGER:<\/span><\/b> Matte black dial with recessed grey subdials and crisp, well-preserved printing. The bicompax layout displays running seconds at 9 o\u2019clock and a 30-minute chronograph counter at 3 o\u2019clock. <\/span> <\/span><\/p>\n

This unique dial configuration boasts a special logo and no model name.<\/span> <\/span><\/p>\n

The yachting regatta scale appears in a slightly \u201cghosted\u201d orange color with black numerals, an unusual and highly recognizable detail.<\/span> <\/span><\/p>\n

The white baton hands, paired with the vibrant orange triangular hand, provide a strong contrast against the dial. They show signs of age like slightly darker lume and flaking orange paint. The Luminous markers are present and show natural aging consistent with the watch\u2019s age. <\/span> <\/span><\/p>\n

CRYSTAL:<\/span><\/b> Acrylic crystal in good vintage condition with minor surface marks<\/span>. <\/span> <\/span><\/p>\n

CASE:<\/span><\/b> 38 mm stainless steel case showing honest signs of wear consistent with age of a tool watch. The case retains a strong overall profile, despite being likely polished in the past, and measures approximately 44 mm lug-to-lug. <\/span> <\/span><\/p>\n

The bidirectional rotating bezel is knurled and correct. The black aluminum insert remains well preserved with light signs of use. <\/span> <\/span><\/p>\n

CASE BACK:<\/span><\/b> Screw-down stainless steel caseback engraved with a prominent penguin motif. The surface is likely polished, and the engravings have mostly worn off but remain somewhat legible. <\/span> <\/span><\/p>\n

The inner side is clean and bears the correct reference and period-correct stamps.<\/span> <\/span><\/p>\n

CROWN+PUSHERS:<\/span><\/b> Unsigned crown, likely a later replacement, and operates as intended. Pump pushers operate correctly and provide crisp chronograph actuation. <\/span> <\/span><\/p>\n

UHRWERK::<\/span><\/b> Gilded, hand-wound Valjoux 23 chronograph movement. The movement is signed, recently serviced, and running well. All functions start, stop, and reset correctly. <\/span> <\/span><\/p>\n

STRAP:<\/span><\/b> 20mm, black \u201cTropic Star\u201d rubber strap with a generic stainless steel pin buckle.<\/span> <\/span><\/p>\n

ZUBEH\u00d6R:<\/span><\/b> Saffiano Leder Uhrenrolle.<\/span> <\/span><\/p>\n

GARANTIE:<\/span><\/b> Wir garantieren die Echtheit der Uhr. Wir bieten auch <\/span>12<\/span> Monate Garantie auf die einwandfreie Funktion dieses Zeitmessers. All guarantees are subject to the General Terms and Conditions<\/span> <\/span><\/p>\n

Please feel free to ask questions; we will be glad to answer. Eine virtuelle oder pers\u00f6nliche Besichtigung ist nach Vereinbarung m\u00f6glich.<\/span> <\/span><\/p>\n","protected":false},"excerpt":{"rendered":"

Introduced during the golden era of multi-purpose tool watches, the Chronomaster was marketed as <\/span>\u201cThe World\u2019s Busiest Watch\u201d<\/span><\/i>, a chronograph designed to serve racing drivers, pilots, divers, and even sailors timing a regatta.<\/span> <\/span><\/p>\n

This particular reference 0\/4076 represents a rare and desirable variant, likely from the early 1970s. It is featured on page 220 of the Chronomaster Only book. <\/span> <\/span><\/p>\n

Powered by the Valjoux 23 and featuring the distinctive stylized \u201cSpecial Logo\u201d and no model name, it stands apart with grey registers and an unusual orange yachting scale with black numerals. <\/span> <\/span><\/p>\n

Collectors also affectionately nickname this version the \u201cPenguin\u201d due to the engraved penguin motif found on the case back.<\/span> <\/span><\/p>\n

Please read the condition report carefully to help you assess the overall condition of the watch.<\/span> <\/span><\/p>\n
