For those of you who don't want to damage your precious luxury watch, we've gathered a selection of hard and durable models!

We've selected five high-end watches that are highly scratch-resistant. These masterpieces showcase each manufacturer's technological prowess, including models made with exceptionally hard materials like ceramics and sapphire crystal, as well as models incorporating unique surface hardening technology.

Scratch-resistant masterpieces put an end to the scratch problem that plagues watch enthusiasts

　Polished by the hands of a craftsman, luxury watches are like pieces of jewelry. When they're new, their shine is truly captivating. However, as you wear your watch on your wrist and spend your days together, one day you might suddenly notice a scratch on your watch that you didn't even notice. The threat of scratches on your watch is everywhere, from when you walk with your arm swinging, to when you accidentally search your bag with your hand wearing the watch, or when you reach into the dispenser of a vending machine. If a watch develops some scratches over the years of use, you might not notice it much, but if it's a scratch that occurred shortly after you bought it, it's even more so. You'll spend your days looking at the scratches with a magnifying glass and regretting it. I'm sure many of you have had the same bitter experience.

　So, this time we'll be introducing some tough watches with highly scratch-resistant exteriors. Today, there are many masterpieces that showcase each manufacturer's technological capabilities, including models made with exceptionally hard materials such as ceramics and sapphire crystal, and models that use unique surface hardening techniques to increase the hardness of stainless steel and titanium. We've put together a wide selection, from affordable watches to high-end complication watches.

Omega "Speedmaster Dark Side of the Moon Apollo 8" Ref. 310.92.44.50.01.001

　The Omega Speedmaster, nicknamed the "Moonwatch," was carried as official equipment on all six of NASA's moon landing projects. Originally launched in 1957 as a chronograph watch for motor racing, the Speedmaster's exceptional durability has seen it travel into space and contribute to the development of human history.

　The Speedmaster Dark Side of the Moon Apollo 8 introduced here is a special model that commemorates the achievement of Apollo 8. The anodized aluminum dial features the surface of the moon, while the movement's base plate and bridges, visible through the see-through back, are laser-etched to depict the reverse side of the moon. The small seconds hand at 9 o'clock is also playful and appealing, featuring the Saturn V rocket used on the mission.

　The case is made of black ceramic. Ceramics is a material that is increasingly being adopted by many brands these days due to its high hardness, corrosion resistance, and scratch resistance. While it may chip if subjected to strong force, with everyday use it should be able to maintain its beauty for many years, comparable to when it was new.

　The movement used is Cal. 3869, a Master Chronometer certified manual-winding chronograph movement equipped with a co-axial escapement.

Sinn "U50.HYDRO.S"

　Sinn has developed a number of unique technologies, known as "Sinn Technology," to create professional watches that function even in extreme environments. The U50.HYDRO.S is a quartz diver's watch that allows you to fully enjoy that technology.

　The black dial, featuring bar indexes and rose-shaped hour and minute hands, offers excellent visibility not only on land but also underwater. The secret to this is "hydrotechnology," which seals a special oil inside the case. This dramatically improves the viewing angle of the dial, ensuring visibility from any angle. Furthermore, this oil makes the contraction rate of the gas inside the case almost the same as that of seawater or freshwater, achieving an extraordinary water resistance of 500 atmospheres.

　The case is made of highly corrosion-resistant U-boat steel and finished with a black hard coating, a combination of Tegiment surface hardening technology and PVD coating. While its surface hardness is comparable to that of ceramic, the PVD coating is highly durable and will not peel off upon impact. The unidirectional rotating bezel is secured with a special side screw fastening system, preventing it from coming off even if the watch is struck against rocks during a dive.

Citizen Attesa "ACT Line Eco-Drive GPS Satellite Radio Wave Watch" Ref. CC4104-53E

　This high-end model is part of the Citizen Attesa ActLine lineup, which is highly popular among active businessmen. The flat case and flowing bracelet give it a sporty look.

　Although it has a striking 44mm diameter, it is lightweight thanks to the use of "Super Titanium™" with Duratect, a proprietary surface hardening technology, for the middle case, case back, and bracelet. The bezel is made of ceramic, a first for an Attesa watch. In addition to its hard and scratch-resistant properties, the strong hairline on the surface also serves as a design accent.

　The rough-textured black dial is inspired by raw titanium. The three subdials are fitted with metal rings, and the metallic flange creates a solid impression that harmonizes with the case.

　It also features many functions, including GPS satellite radio wave reception, solar-powered Eco-Drive, perpetual calendar, chronograph, double direct flight for easy time zone adjustment, and alarm.

Panerai Submersible BMG Tech™ 3 Days Automatic Ref. PAM00692

　BMG Tech™ is a bulk metallic glass that is given a random atomic structure through a rapid cooling process and high-temperature, high-pressure injection process. The Submersible BMG Tech™ 3 Days Automatic is the first mechanical watch to feature BMG Tech™ for its case, bezel, crown, and crown protector. Its unique molecular structure makes it harder and lighter than stainless steel, while also providing excellent corrosion resistance.

　The case measures a massive 47mm in diameter. Its design, including a combination of dot and bar indices, a deep blue dial, and a solid unidirectional rotating bezel, is typical of a diver's watch, but the crown protector and small seconds at 9 o'clock add a unique touch. The case back is made of titanium.

　The watch is equipped with the automatic Cal. P9010 movement, which boasts a practical power reserve of approximately 72 hours thanks to its two barrels. The hour hand can also be moved independently in one-hour increments, making it easy to adjust for time differences when traveling to different time zones.

Girard-Perregaux Quasar Light Tourbillon with Three Bridges, Ref. 99295-43-3313-5CC

　The Quasar Light Tourbillon with Three Bridges is a tourbillon complication watch that incorporates the iconic Three Bridges design of Girard-Perregaux. The case and the three bridges visible from the dial are made of sapphire crystal, allowing a large amount of light to enter, revealing the internal mechanism in detail.

　The tourbillon, which appears to float and is supported by a barrel at 12 o'clock and a sapphire crystal bridge at 6 o'clock, allows viewers to enjoy its dynamic movement. The movement can also be viewed from the case back, allowing viewers to appreciate every last detail of the mechanism, including the winding mechanism, beveled baseplate and bridges, gears, and micro-rotor.

　The watch is fitted with a fabric-like rubber strap, a pure white finish that complements the luminous sapphire crystal case, and a grade 5 titanium folding buckle for secure and easy removal from the wrist.
