Octo Finissimo Perpetual Calendar Tantalum Only Watch 2021 is the very long and descriptive name of this unique timepiece donated by the Roman firm and Swiss manufacture for this year’s Only Watch charity auction.

This long name of this Bvlgari does not hide anything. It tells us the collection (Octo) to which the watch belongs. It tells us the complication it brings us, the perpetual calendar. It tells us the material with which its case is made, tantalum, which in this case is the differential factor of this watch. Finally, it points out that it is a piece created for the 2021 edition of the Only Watch auction.

For this edition of the Monegasque charity auction, which is held biennially, Bvlgari has decided to put a lot of meat on the grill and has not limited itself to decorate some external element of a known watch with the color of the Only Watch. This, although very discreetly it has done, but the transcendent thing is the rare metal used to make its case, tantalum.

The characteristics of tantalum are very peculiar and special, both aesthetically and technically. It is a metal with the symbol Ta in the periodic table of elements. Its specific gravity is very high, practically equivalent to that of gold, which at functional and technical levels makes it a very special metal.n a watch implies that it will be extremely heavy.

A priori, this physical characteristic of tantalum can not be considered as something beneficial to elaborate the case of a watch, but there are always people who prefer to “feel” their watch on the wrist. This is not an uncommon preference since on a subjective level the weight always conveys a greater sense of quality.

Another characteristic of Tantalum is its high hardness, higher than steel or titanium and of course than any gold. This characteristic is positive in the sense that it is highly resistant to scratches and shocks, but at the same time implies a greater difficulty of mechanization so the production cost is higher than that of the aforementioned metals. If we add to this the high purchase price of tantalum, the watch that uses it to make its case will be much more expensive than its equivalent in steel or titanium.

For all these reasons, there are very few and very special watches throughout history that have used tantalum. I can think of a Seamaster edition from Omega, a Big Bang from Hublot, a Royal Oak from Audemars Piguet, a Quai de l’Ile from Vacheron Constantin and a Montblanc. It’s possible I’ll forget some, but they’ll be few.

The basis thate has chosen Bvlgari to make this unique piece is that of the Octo Finissimo Perpetual Calendar, the watch that was presented to us in April of this year. As has been the case with every edition of the Finissimo, at just 5.8 millimeters thick, the Perpetual Calendar once again broke a record and was proclaimed the thinnest automatic perpetual calendar in the world. We have published an extensive article on this important novelty, in which we analyse all its details in depth.

All the physical and technical characteristics remain unchanged with the exception of two details. The first and most relevant is the tantalum used to manufacture the case. In addition to the physical qualities that we have already mentioned about this metal, we must also note that it provides a very special aesthetic feature; the unmistakable bluish tone that it gives off, something that will allow people with good knowledge of watchmaking and / or metals to identify it. As you can see in the pictures, like all Octo Finissimo, the case is sandblasted.

The second feature that differentiates this Octo Finissimo Perpetual Calendar Tantalum from its regular production brothers are some aesthetic details made with the orange tone of the Only Watch. The first and extremely discreet is found on the dial, specifically on the dial that indicates the month. In it we will see that to indicate the month of November have been changed the typical acronym NOV by NOW. The first reason is that the auction will be held in November, specifically on the 6th. The reason for the replacement is that this way we get the acronym OW (Only Watch) which is decorated with the orange color that we have mentioned.

The second aesthetic detail is this same orange tone that we also find in the term “ONLY WATCH” printed on the sapphire crystal of the back of the watch. This detail is no longer as discreet, but with the watch snug on the wrist it will never be seen.
