Hanging high above, its circular dial emanates a simple yet elegant aura. The black hour and minute hands glide smoothly across the pristine white surface, marking time with precision. The clock’s outer frame is made of sturdy metal with a smooth surface reflecting the surroundings. The vibrant red second hand, resembling a conductor's baton, draws a brilliant arc through the flow of time.

Since its introduction in 1953, the Swiss railroad clock has not only served as a timekeeping instrument but has also become a symbol of Switzerland.

Inspired by the Swiss railway clock, the designer has crafted the AMT258 with a conductor's baton red second hand, bar-shaped hour and minute hands, and linear markers, giving it a unique soul shaped from titanium. As the fourth generation of the BERNY railway clock collection, the AMT258M is not only the first watch in the series made from titanium but also innovatively combines brushing, sandblasting, and polishing techniques, showcasing exceptional watchmaking craftsmanship.
Three types of dials
The watch is available in three variants, all in the classic black, white, and red color scheme.
AMT258MS-A: titanium gray case + black dial + white indexes and hour and minute hands + red second hand
AMT258MS-B: Titanium gray case + silvered smooth dial + dark gray indexes and hour and minute hands + red seconds hand
AMT258MS-L-B: titanium gray case + white dial (with subtle leather-like texture due to luminous powder) + black indexes and hour and minute hands + red seconds hand
Titanium-Based Alloys
Grade 3 Titanium, also known as "Ti-3", is a commercially pure form of titanium. This material is widely used for its balanced properties, especially in applications requiring moderate strength, excellent corrosion resistance, and good weldability.
Physical properties
- Density: 4.5 g/cc or 0.163 lb/in³
- Hardness: Brinell 225, Knoop 175 (unwelded sample), Knoop 220 after welding
- Tensile strength: Ultimate 440 MPa (63,800 psi), Yield 377 - 520 MPa (54,700 - 75,400 psi)
- Melting point: 1,660 degrees Celsius
- Elongation: 18 %
- Area reduction: 35 %
- Modulus of elasticity: 105 GPa (15,200 ksi)
Main features
1. Lightweight: The density of grade 3 titanium is about 4.5 g/cc, which is about 40% lighter than stainless steel
2. High strength: Despite its light weight, grade 3 titanium is very strong, providing good durability and pressure resistance
3. Corrosion resistance: Excellent resistance to corrosive liquids such as seawater and sweat
4. Anti-allergic: lightweight good biocompatibility and will not cause skin allergies even if worn for a long time.
5. Welding performance: Compared with other titanium alloys, Grade 3 Titanium can be welded more easily, which helps to maintain the integrity of the structure in complex designs.
6. Processability: It can be processed in various ways, such as polishing, brushing, etc., to create different appearance effects
The case of the AMT258M Men's Mechanical Titanium Watch is polished on the bezel, satin-finished on the lugs, and sandblasted on the sides. The satin finish is also applied to the case back with an elegant sunburst pattern. The rich layers of texture make the watch ornamental while minimizing fingerprint traces and contributing to a neat and presentable appearance.
Titanium bracelet & quick-release canvas strap
Each can be purchased separately in the store.
Titanium bracelet and safety folding clasp
The titanium alloy bracelet is suitable for sensitive skin due to its excellent biocompatibility, and it also features corrosion resistance, effectively guarding against the effects of sweat. The matte surface of the strap enhances skin-friendliness. The links are removable, and the buckle is adjustable to fit wrists of different sizes. The double-press mechanism allows for easy removal, while the safety clasp prevents it from falling off.
Quick-release canvas strap and pin buckle
The canvas is breathable and lightweight, definitely lighter than a titanium alloy strap, with the whole watch weighing only 57g! The quick-release function makes it easy for us to switch between different straps to match our daily outfits. By the way, the pin buckle is just perfect!

About Super Luminous
2. Green luminous for indices and hands (super)
3. Blue luminous for full dial
Super Luminous used by BERNY
Luminous powder from NEMOTOLUMI PRODUCTS (SHEN ZHEN) Co., Ltd. is a non-radioactive light-storing material, the main component of which is aluminate.
It was in the 1990s that NEMOTO & CO., LTD. invented and innovated this long-lasting, bright, and safe luminescent material. The company also developed and patented the famous Luminova & Super-LumiNova.
10ATM Waterproof
The AMT258M, with a 10ATM water resistance rating, supports water activities such as swimming and snorkeling. It's not just a versatile everyday watch; thanks to its robust titanium material, strong luminescence, and 100M water resistance, it is also suitable for sports and outdoor scenarios.
