The term "sector dial" is somewhat vague, and the exact definition can vary depending on whom you ask. As a result, manufacturers can incorporate a lot of elements in its design. In general, when I look for a sector dial, I look for watches with concentric outer rings. On one of these rings, five-minute markers are typically located, while the other features one-minute markers. Additionally, the center of the dial should have a clean appearance. A date window or a similar complication is acceptable, but there should be no more than one. The idea is for the design to draw the eye to the outer rings.
Sector dials are sometimes called "scientific dials" or "railroad dials." However, a railroad dial is not the same as railroad watches. Railroad watches are high-precision timepieces made for railroad workers to keep trains running on time. A railroad dial simply refers to the segmented appearance of the outer rings of many sector dials, which resemble railroad tracks with minute hashes laid out like railroad ties. Now that I've cleared up potential confusion, let's move on to the review.
Jaeger-LeCoultre Master Control Date
The Jaeger-LeCoultre Master Control Date Sector Dial is a mid-sized watch, 39mm in diameter, with a moderate thickness of 8.5mm. The case is made of stainless steel, featuring a rounded polished bezel and matte sides. This naturally draws attention to the top of the watch, while the sides have a relatively subdued look. The sapphire glass is flat, again drawing attention to the dial itself rather than other elements.
The dial is restrained, with a silver finish and a date located at the “3 o'clock” position. The inner index has long black hashes with numerals at the “6”, “9”, and “12 o'clock” positions. The outer index has smaller markers indicating individual minutes. Five-minute marks are indicated by blue arrows, which are small enough to add an attractive accent without being distracting. The hour and minute hands are skeletonized, with narrow tips, and the second hand is long and very thin.
The movement is the automatic JLC Caliber 899/1, manufactured in-house by Jaeger-LeCoultre. It has a 38-hour power reserve and operates at 4 Hz. A superb rotor made of pure gold is perfectly suited for viewing through the Jaeger display back. The rotor occupies one-third of the space, while the other two-thirds allow a good view of the steel interior components.
The Master Control Date Sector Dial is water-resistant up to 50 meters, making it suitable for showers and other light water contact. These are wonderful collectible watches, but they are not diving watches. The black alligator leather strap is elegant, with a simple clasp that's easy to open and close.
Longines Heritage Classic
The Longines Heritage Classic Sector Dial is a 38.5mm stainless steel watch with an elegant, rounded design. As we will see, everything about this watch is round, which blends well in a cohesive look. The sapphire glass is slightly raised, with a sharp bevel on the outer side. It is scratch-resistant, and its underside has a multi-layer coating to prevent glare.
The watch's silver dial features a black cross in the center, dividing it into four quadrants. The outer ring is a darker silver than the center, with large ticks at the five-minute markers, connecting the central area to the watch's outer edge. Smaller one-minute markers are located around the outer circumference, with bold numerals at the “3”, “9”, and “12 o'clock” positions. The hour and minute hands are almost the same length, made of blue material for good visibility. Instead of a second hand, there is a small 60-second subdial at the “6 o'clock” position.
The automatic L893 caliber movement is well-constructed, with a frequency of 25,200 beats per hour. This is slower than many automatic movements, but only slightly. If you enjoy hearing your watch tick, this unusual frequency makes them a great choice. Additionally, the power reserve is 64 hours, which is enough to set the watch aside for a few days without needing a reset.
Like most sector dial watches, the Heritage Classic Sector Dial is not intended for water use. The watch is rated for 20 meters of water resistance, making it splash-proof. Wear it in the shower, but remove it if you're going swimming. The watch comes with a black leather strap with a flat, smooth surface and small steel clasps at the lugs.
Vacheron Constantin FiftySix
The Vacheron Constantin FiftySix 4600E/110A-B487 is a medium-large watch with a diameter of 40mm and a thickness of 9.6mm. This makes the watch look great on the wrist, and the display case back provides an attractive appearance when the watch is not on the wrist. The outer edge extends almost to the end of the crown, providing some security, and the flat sapphire glass is scratch-resistant and anti-reflective.
The dial is royal blue with silver indexes and hands. Large hashes mark the five-minute points, and large numerals are located at the even hour positions. At the “3 o'clock” position is a small date window, which is a bit too small for easy reading but adds a nice accent. The outer index has small hashes at all 60-minute marks, and the circular lines on the inner and outer side create a "railroad track" impression. The hour and minute hands are relatively wide, with white luminescent stripes down the center, and the second hand is very thin and exceptionally long.
The Constantin FiftySix uses the Caliber 1326 movement, specifically designed for creating a beautiful display view on the FiftySix showcase. It operates at 28,800 beats per hour, has 25 jewels, and a solid 48-hour power reserve. The gold rotor features a large Maltese cross, which is also the Vacheron logo. It is mostly transparent, allowing a good view of the entire mechanism.
The FiftySix is water-resistant up to 20 meters. In reality, this is not water resistance but splash resistance. Do not wear them while swimming, or you might ruin your investment. The strap is sturdy and attractive, with a 5-link construction that makes it exceptionally flexible. However, like any other metal watch strap, you will likely need a custom fit.
Laurent Ferrier Galet Square
The Laurent Ferrier Galet Square Sector Dial has a square case, as the name suggests. Its size is 41mm on each side, with a rounded bezel that smoothly transitions into the domed sapphire glass. This gives the watch a thick, embossed profile, but not so curved as to distort the view of the dial.
The dial itself is available in 7 different color options, from rose gold to black and dark blue. Depending on the variant, the case is made of stainless steel or rose gold, though they all share the same profile. The inner index has large hashes at the five-minute marks, with no numerals cluttering the design. The outer index is designed as a railroad track, with tiny numerals marking the 5-minute points. The minute hand is long and thin, while the hour hand is short, with a long spear-shaped tip. At the “6 o'clock” position is a small 60-second subdial with a hand extended to the edges.
The automatic Caliber FBN 229.01 movement is quite precise, although the unidirectional micro-rotor means the time can only be set in one direction. Be careful when setting the time. If you go one minute forward, you will have to set the time to 29 hours and 59 minutes to go back to the correct position. At the same time, it is an in-house manufactured movement, so it is more finely made than most off-the-shelf movements.
These are not waterproof watches. Unfortunately, you cannot take them swimming or even in the shower. If you spend a lot of time in the water, you will probably need a different watch. The brown leather strap has a working look, with dense stitching along the outer edges that makes it more durable and serves as an accent.
Patek Philippe Calatrava
The Patek Philippe Calatrava Sector Dial watch has a beautiful round shape, 38mm in diameter, and 8.43mm thick. The watch features a sloped bezel and sapphire glass that is scratch-resistant and anti-reflective. The case back is also made of sapphire, allowing an unobstructed view of the movement.
The white dial has a clean appearance, with no complications other than a small date window at the “3 o'clock” position. The inner index has large wedges marking the 5-minute points, and larger wedges at the quarter-hour marks extending beyond the index. Smaller hashes mark individual minute points. There is also a narrow outer railroad-style index with hashes marking individual minutes. Small numerals mark the 5-minute points. The hands are wide and spear-shaped, with a black coating that sharply contrasts with the dial. The second hand is absent, further emphasizing the clean look of the Calatrava.
The automatic Caliber 324SC movement has 29 jewels and beats at 28,800 beats per hour. The power reserve is 45 hours, so you can take the watch off for almost two days without any issues. The Calatrava is water-resistant up to 30 meters. As with the other watches I've discussed, this means they are splash-resistant, suitable for showers but not for swimming. The black alligator leather strap is durable, with decorative stitching along the outer edge.
