IWC Colonial Annual Calendar

Once we told you last week, IWC replica is going to be debuting their overhauled Portuguese collection from SIHH. For their brand new Yearly Diary, IWC required to create a new automatic movement. The end result is in-house caliber 52850 which operates at 4Hz, offers 36 jewels as well as has a seven-day (168-hour) energy book.

The brand new quality features upgrades that’ll be seen over the whole 52000 caliber loved ones. Such as a thinner blades, and also the links that are more open up – allowing additional information to become noticeable with the open caseback. The actual links are inset with a solid gold “Probus Scafusia” medallion. There is also an improved Pellaton turning program with a digital wear-totally free element made of monochrome ceramic.
The night time azure dial/metal design (proven) features a sunburst finish, accented by gold polished, leaf-formed hour and moment hands, gold refined applied Arabic numbers, silver polished additional hands against the circular guilloche pattern. Lustrous hr indices. Print styles are printed in white.

As the motion is complex, the call design is anything but. The purist style includes a multiple diary indication (from 12 to’time clock) for that 30 days, day and day, each using their own aperture. Additionally, the timepiece shows hours and moments through the centrally installed subsidiary dials for small seconds (from nine o’clock) as well as remaining energy reserve (at 3 o’time clock).

The actual diary switching system instantly changes for that various number of days every month, however, in contrast to a perpetual diary it is unable to result in the adjustment for Feb or take into account if it is the leap year. Therefore, it must be manually corrected as soon as in February, and when throughout a leap year.

According to IWC, “To add mass to the annual calendar module, IWC’utes watch creative designers made certain how the modification could be carried out easily as well as conveniently using the crown. Because of this elegant solu- tion, the engineers were able to spare the corrector, which may possess compromised the actual Portugieser Yearly Diary’utes purist style.”

The crown is actually non-locking, refined as well as features a relief etched “Probus Scafusia” logo. And, thanks to the revolutionary movement style, no recessed caseband pushers are needed to correct the annual calendar. Instead, just about all functions are controlled through the overhead.
The IWC Colonial Annual Diary will come in steel, in either the midnight azure (Referee. IW503502) or a silvered call (Referee. IW503501), and in 18K red-colored gold having a silvered call (Referee. IW503504). The case measures forty-four.2 mm through fifteen.three mm and it is completely refined having a slim set frame

The 3 references come with a dark alligator straps as well as folding clasp. Water-resistance is 30 yards. An arched advantage sapphire crystal with zero-refractive coating on both attributes safeguards the call.
