The 2017 Anonimo Nautilo Bianco is a 44.4 mm automatic dive watch distinguished by an opaline white dial and a choice of grey or black ceramic bezel. Its launch specifications include 200 m water resistance and a Sellita SW200-1 movement. The prices often quoted for it—CHF 2,150 or USD 2,290 for the grey version, and CHF 2,190 or USD 2,350 for the black—were launch prices, not current price guidance.
What the 2017 Nautilo Bianco is
Anonimo introduced the Nautilo Bianco in 2017, its 20th-anniversary year, as a white-dial addition to the Nautilo diver family. The launch coverage presented the light dial as a deliberate alternative to the dark faces common on dive watches. Its defining details include an opaline white dial, applied metallic luminous markers, and the line’s triangular marker arrangement at 12, 4 and 8 o’clock.
The watch has a cushion-shaped case and a crown at 4 o’clock, protected by an extended guard. That combination gives the Bianco a distinctive, substantial profile rather than the familiar round-case diver look.
Grey and black launch versions
The two 2017 executions share the same core specification, but differ in bezel finish and treatment of the case. The black model does not have an entirely black-coated exterior: its central case container is black DLC-coated, while the crown, crown-protection device and lugs remain uncoated.

How the white dial and case wear
In its launch review, Monochrome’s author judged the 44.4 mm watch fairly wearable despite its diameter, crediting the cushion-shaped case. That is a reviewer’s impression, not a guarantee of fit: wrist size, case proportions and personal preference all affect how a watch of this diameter feels.
The same reviewer found the contrast between the white dial and dark hands and indexes effective, describing legibility as good in both daytime and nighttime conditions. The article does not provide a quantified legibility test. The luminous markers and high-contrast layout support the watch’s practical diver character, while the white face gives it a brighter, less conventional appearance.

Movement and brand context
The listed Sellita SW200-1 is an automatic movement with a 38-hour power reserve and a date display. Anonimo’s official brand page says the company was founded in Florence in 1997, that military engineer Dino Zei developed the Nautilo line after joining in 2003, and that the company has been headquartered in Switzerland since 2013. The brand also states that Sellita produces its Swiss-made automatic movements and identifies the SW200-1 as a movement used in Nautilo and Epurato watches.
Those statements provide context for the model’s Italian design identity and Swiss movement, but do not establish the Bianco’s current production or retail status. Anonimo’s official wording is: “All ANONIMO watches are equipped with Swiss Made automatic mechanical movements produced by the independent Swiss manufacturer Sellita.”

Price and availability today
The 2017 launch prices are useful for understanding how the two versions were positioned at introduction, but they should not be used as a present-day valuation. Current retail pricing, production status and live listings for the exact Nautilo Bianco have not been verified here. Anyone considering a purchase should confirm the reference, condition, included strap and accessories, seller terms, and current price directly with the seller.
Do not confuse it with the Nautilo Vintage White
The 2017 Nautilo Bianco is not the same watch as the Nautilo Vintage White, reference AM-5019.19.241, reviewed in 2020. Time and Watches gives that separate model a 42 mm case and reports a CHF 2,290 price on strap. It also describes wearing that Vintage White for a week. Those details apply to the 2020 model, not the 44.4 mm Bianco discussed here. See Time and Watches’ review of the Nautilo Vintage for that distinct watch.
