Bulova Accutron has introduced its new breakthrough timekeeper that was first presented this spring at the Baselworld 2012 fair. The most interesting thing about the new Bulova Accutron Calibrator is that it has a proprietary External Fine Adjustment System (EFAS). This original feature allows the wearer of the watch to adjust the functioning of the watch’s automatic mechanical movement on his own, without the help of a professional. Each of Bulova Accutron Calibrator timepieces is equipped with a special key that is used to adjust the length of the hairspring, and thus adjust the pace of the movement in order to improve its accuracy.
In its heyday during the sixties, Bulova started producing revolutionary Accutron tuning-fork watches that were unprecedented for its accuracy when they emerged. However, the first electronic watches were relatively soon overran by the emergence of the quartz-based calibers that were a lot simpler and cheaper to make. In 1977, Bulova stopped producing timepieces with tuning-fork mechanisms and switched to the quartz ones, thus losing a great deal of its exclusivity. In a clear effort to associate its name with the horological advantages, Bulova Accutron has launched a new timekeeper named Calibrator. With its novelty External Fine Adjustment System, now every owner of the watch can tune his automatic watch and adjust its pace. For this purpose, the new timepiece has seven different hairspring length modes, each of them corresponding to the pace that is five seconds a day faster than the previous one. The different modes are activated by a special device that appears like a key which is inserted in the correct opening at the left side of the case, and turned to select a different pace of the caliber, as it is indicated on the retrograde sub-dial that sits at the nine o’clock position.
A Medium-Sized Steel Case with Exhibition Back and a Reserved Design
Currently, there are three variations of the Bulova Accuton’s technological break-through timekeeper. Each of them has the same basic features. The housing of Bulova Accuton Calibrator watch is circular in shape with the width of 43mm and the thickness of 12.5mm. At the front of the watch with the fixed bezel stands the flat anti-reflective crystal made of sapphire. At the other side, the new Bulova Accutron has an exhibition case back attached with four screws. The featured water resistance is 50 meters.
A look at the dial of the watch shows that the brand also tried to pair the technological advantages with a refine design. Bulova Accutron Calibrator timekeeper has a three dimensional dial with different patterns as decorations for the central part, the outer segment and the EFAS sub-dial. Besides, the watch sports nice looking Arabic numerals, skeleton hour and minute hands with luminous tips, a sweeping central second hand, and a scale on the outer part of the dial that is divided to increments corresponding to 1/5th of a second periods. Additionally, there is a date aperture at the traditional three o’clock position. This date display is the only additional feature of the watch with the external fine-tuning system. The watch is made with a self-winding mechanical movement which is, like all of the brand’s calibers, Swiss made. In the accordance with what is unfortunately the common practice of the manufacturer, it is virtually impossible to figure out the exact caliber type and its specifications.
A Silver-White or a Black Dial
As we have previously noted, there are three variations of the timekeeper. The first one with the reference number 63B160 is made with a silver-white dial and paired with a brown leather strap. Likewise, a silver-white face is featured on the second version with the designation 63B161, but in this instance, it is combined with a five-link stainless steel bracelet that features two raised rows which give it a three-dimensional appearance. The last model is the 65B148 that unlike the previous ones sports a two-tone case (silver and red gold colors), red-gold colored accents on the black dial, as well as a black leather attachment. In each of the variations, the wristlet fasten with a deployment buckle.
