Corum has added another highly impressive timepiece to its palette of products. The latest newcomer by the Swiss firm is called Admiral’s Cup Seafinder 47 Tourbillon Chronograph. This truly extraordinary piece features several impressive technical traits. For starters, it includes a one-minute tourbillon complication with an oversized cage. Moreover, it has automatic winding, a column-wheel chronograph and it possesses improved resistance. The watch comes in recognizable and nautical inspired twelve-sided case which is often used in the watches from the Admiral’s Cup series. Available materials for the housing are aluminum with ceramization treatment and red gold, while the gold version can be additionally embellished with three different levels of round and baguette-cut diamond decorations for those who require even higher level of luxury.
Accurate, Resistant & Traditional
Caliber CO 398 used in Corum’s novelty combines demanding features. In a less likely fashion, it combines a tourbillon feature with automatic winding which allows much more stable rate. Additionally, the movement features the higher frequency of 4 Hz which contributes to its increased accuracy. Its oversized tourbillon cage with the diameter of 14.08 mm which features the brand’s key shaped logo is attached to a micrometric triple screw which enables finer adjustment and additionally lifts the precision. Finally, the fact that Caliber CO 398 is a lever escapement movement that has pallets made of Glucydur alloy considerably raises its resistance and makes the watch altogether much more durable and suitable even for a dynamic lifestyle.
CO 398 has 28 jewels and it incorporates a traditional solution when it comes to its chronograph complication. It has a more demanding and more valued column-wheel type of chronograph. The complex movement is 16 1 lignes wide, while its power storage lasts for 45 hours.
It is of upmost importance to likewise say that all of the components to the movement are polished and chamfered by hand. This sort of approach includes that the functioning parts are made only slightly larger than they need to be (and we are talking about fractions of millimeters). These components are then manually polished by a skilled watchmaker that leads to them looking better and eventually being reduced to the proper size. There are further decorations visible on the movement which is exposed through the transparent smoked sapphire back (by the way, sapphire with glare-proofed treatment is also used for the crystal on the front side). Among them there are straight graining, circular graining on the base-plate, bridges and screws, as well as ruthenium treatment utilized for coating of the oscillating weight of the movement’s winding system.
Guilloche Brass Dial
Another uncommon trait is the position of the tourbillon cage on the watch’s brass dial with a checkered guilloche pattern (the dial can be in gray or black color). Unlike at the very bottom, which is usual, this watch has its tourbillon cage placed at the ten o’clock position, which was previously seen in various other models from the Admiral’s Cup lineage. Since it is the tourbillon whose rotational period lasts for exactly one minute, it is also used to designate seconds. Moreover, the dial includes two additional indications: a 60 minute sub-dial at the bottom and a date counter on the right side. Apart from these, it should be said that the watch also has large skeletonized hands with luminous tips, applied hour markers, sword-shaped pointers for the counters that resemble the indication of a compass, as well as a discrete minute scale with nautical pennants on the flange.
Ceramicized Aluminum or Red Gold
The 12 sided (dodecagonal) housing of Corum Admiral’s Cup Seafinder 47 Tourbillon Chronograph is not only peculiar because of its shape, but also because of the material used for its construction. One of the versions of the timekeeper has its case made of aluminum that received a ceramicized charcoal gray treatment which makes the material exceptionally sturdy and tougher than the usually utilized stainless steel. More importantly, it is ten times more longevous than steel, as well as anti-abrasive and corrosive-proof. The process that is used for the making of ceramicized aluminum is called micro-arc oxidation (MAO) which was initially discovered over a half century ago, but only recently perfected and made more usable. It involves chemical, physical and electrical transformation of the base material aluminum which is submersed in water. The final product is durable, but also very pleasing on the eyes and comfortable on the wrist.
Apart from the ceramicized version, there is also an option to get a watch in housing made of 18 K red gold. Despite the material, the dimensions remain the same and they are: the diameter of 47 mm (as it is clear from the watch’s name) and the thickness of 15.72 mm. This is also the case with the waterproofness that measures to 50 meters.
When it comes to difference between the ceramicized aluminum and the red gold version, one can quickly notice that they have different colored dials. While the former one has a gray face with the matching appliqués and hands, while the latter has a black dial with markers and hands that match the color of the case. Moreover, ceramicized aluminum one has its crown protector from the same material as the case, while its crown (which is in all instances decorated with the engraving of the brand’s logo) and pushers are made from grade 5 titanium. For the gold version, all of these components are from the same material as the case.
Three Additional Jewelry Versions with Round and Baguette Cut Diamonds
If this highly complicated newcomer from the Corum’s Admiral’s Cup series is not lavish enough for you, there are three additional jewelry versions of the red gold model with different levels of embellishments. What is common for all three of them is that they have a bunch of round-cut diamonds on its chrono minutes and date sub-dials (88 weighing 0.13 carats) and nine baguette-cut stones used on the hour markers. The differences among jewelry models are reflected in the type and the amount of stones which were used to engrace its fixed bezel, lugs and crown protector. The first includes solely round-cut gems, more accurately 204 of them with the total weight of 2.13 carats. Next, we have a version which is decorated with 36 baguette-cut precious stones on the bezel (4.71 carats), as well as with the additional 144 round-cut diamonds (around 0.63 carats) on its lugs and crown protector. The third extra lavish version features the most baguette-cut diamonds. There are 60 of these sparkling stones on the bezel and the lugs (weighing around 6.01 carats), while the round-cut stones are found only on its crown guard (36 diamonds which weigh around 0.05 carats).
When it comes to the attachment of Corum Admiral’s Cup Seafinder 47 Tourbillon Chronograph, the strap of choice is a black crocodile leather strap with a tongue buckle in the material of the case. There is still no official information regarding the pricing of the model. However, considering its technical complexity, even the most basic of the versions without any diamond ornaments will be available only to the selected few.
