Hands-on: De Bethune DB28 steel wheels blue "hour glass"

The skeleton is dressed in blue.

De Bethune is the newest of many watch manufacturers and stands out to commemorate the 40th anniversary of Singapore's watch retail giant The Hour Glass. De Bethune took the opportunity to combine its iconic DB28 variant with spring lugs, which are completely covered with bright blue titanium.

Steel Wheels debuted in a polished titanium alloy in 2018. It is essentially a DB28 with less wear. The partially hollowed out dial-actually a triangular barrel bridge-reveals a pair of hollowed barrels and gears.

The original Steel Wheels captured the essence of De Bethune and combined its trademark design with the brand's basic technological innovations, but lacked a large amount of blue titanium alloy, which is synonymous with the brand.Hublot Big Bang Meca-10 Ceramic Blue 414.EX.5123.RX

DB28 Steel Wheels Blue has now been corrected, which can be said to be the purest and most melancholic sublimation of the brand's core values ​​and technical achievements.

It has a strong mirror-polished blue titanium case and dial, which contrasts sharply with the exposed internal machinery. Although blue titanium is also used by other brands today, De Bethune took the lead in mirror-polishing the titanium case and, more importantly, began heat treatment of blue titanium as early as 2006.

All parts of the watch (including steel and titanium) are first mirror polished, thoroughly cleaned, and then baked in an oven at 700°C to obtain a striking uniform blue shade.

Because the blue is done by hand, the blue color is not exactly the same on the entire surface, especially on large components like this. However, the change is small and can be ignored, and the shadow color and characteristics of the watch are also increased.replica watches for sale

The gorgeous titanium blue case has only one practical disadvantage: the blue surface is the result of oxidation of the metal surface, which means it is prone to chips and scratches, and often causes the natural gray of titanium to show through blue.

The DB28's shell is also all titanium and is equipped with spring-loaded hinged lugs, making it large, light and ergonomic.

The case has a diameter of 42.6 mm and a height of 9.3 mm-large, not bad, but at the same time slender and elegant, thanks to the polished surface and the delicate appearance of the hollow lugs.

Most importantly, the brand's patented lugs ensure that the case fits snugly against the wrist. The lugs also mean that the wear of the watch is much smaller than the given case size. De Bethune also offers two lug lengths, with shorter lugs suitable for smaller wrists.

Thanks to the articulated lugs, the crown is located at the 12 o'clock position, giving a symmetrical case profile.replica luxury watches

It is more practical to use blue titanium on the components in the case, and there is a lot of content here.

The chapter ring and hour ball are made of blue titanium, while the minute hand is made of blue steel. The most unusual is the hour hand, which is marked with a sapphire crystal and is inlaid with a blue steel central strip and frame.

The uniqueness of the steel wheels-all other DB28 models have a solid dial-the triangular barrel bridge and part of the dial have been hollowed out to expose the gears below. The barrel and ratchet have also been carefully crafted to bring lightness, airiness and mechanics to the dial.

The triangular-shaped bridge is also decorated with Côtes De Bethune's "shimmer" engraving (basically a small-scale engraving done by machinery), which uses Geneva stripes.

The traditional Geneva ripples are easy, but Pod Bethune's stripes are clear and sharp. It does add extraordinary depth and texture to the dial, but the engraved stripes look clearly mechanical and eye-catching, and feel much more refined than the other components of the watch.Richard Mille RM 52-05 Pharrell Williams

The watch is powered by a manual winding movement. There are five internal innovations in DB2115V4, three of which have been patented and can be seen from the front.

Every aspect of the transmission system from barrel to hairspring has been optimized to improve performance at the most basic level.

A pair of barrels can be seen on both sides of the triangular bridge, which can provide a power reserve of six days. According to the brand, six jeweled blades are installed on both sides of the barrel to minimize the friction between the barrel and the barrel and optimize energy transfer.

The escape wheel made of silicon further complements the escape wheel, which has almost no friction and requires very little energy, less than one third of the density of steel. Although the service life and future of silicon components have always been the concerns of small independent brands.RICHARD MILLE RM 35-02 Rafael Nadal Quartz-TPT Red

It is worth noting that De Bethune is still one of the very few independent watchmakers that adopt silicon technology without worrying about retaliation by major companies that have most of the patents related to silicon watch parts. In fact, De Bethune was the first brand in 2008 to incorporate silicon into a balance wheel, combining it with heavy metals such as platinum to achieve the ideal mass inertia ratio.

After the escapement, the drive chain is followed by a patented high-performance balance wheel, which is fixed by a polished blue bridge on the side of the brand's patented "triple ramp" shock absorber. It is essentially a pair of extra springs that complement the regular Incabloc shock protection for the balance staff, so it is the nickname of the "triple ramp".

The balance is made of blue titanium and is equipped with platinum on its periphery to adjust the weight. The weight on the rim provides sufficient vibration inertia, while the low density of titanium reduces the overall weight. Its design has also been optimized to improve aerodynamics and thermal stability.Richard Mille RM 52-05 Pharrell Williams

The balance spring is made of Nivarox, which is a nickel-iron alloy commonly used in most movements. However, its uniqueness lies in the unique terminal curve formed inside De Bethune's watchmaker. Compared with the Breguet coil, the balance spring is flat, but the end curve is wider, which can reduce the height and improve the concentricity.

Finally, at 6 o'clock is De Bethune's modern spherical spherical moon, which consists of two hemispheres-one in palladium and the other in blue steel. According to watchmaking industry standards, it can maintain accuracy within one day every 122 years.

Although all the key elements of the movement are visible on the dial, the only functional function located on the back is the power reserve indicator with its elongated frame and blue hands.

DB28 Steel Wheels Blue (DB28 Steel Wheels Blue) has a contrasting color and a hollow dial, which may be suitable for a brand that focuses on technical engineering to attract the most critical innovation that De Bethune has never seen before.

The blue titanium case (this unique feature defines the brand) is the final touch it needs to become one of the most complete and important De Bethune watches.Jacob & Co. Astronomia Clarity AT120.40.AD.SD.A
