Built for underwater performance, the Oshoro Collection is engineered as a professional dive watch with capability at its core.
Designed to perform in demanding conditions, it combines technical precision with purposeful design to deliver confidence at depth and versatility in everyday wear.
Its 316L stainless steel case is built for strength, corrosion resistance and lasting comfort. Defined by balanced proportions and refined finishing, it offers a strong presence on the wrist while remaining practical for daily use.
The dial is designed for immediate legibility. Applied indices and distinctive hands ensure clear reading in changing conditions, with a clean and functional layout that prioritises clarity above all else.
Water resistant to 300 metres (1,000 feet), the Oshoro Collection is built to meet the demands of serious diving. The unidirectional rotating bezel allows precise measurement of elapsed time and provides dependable operation when timing matters.
Finished with a choice of bracelet or strap, the watch is designed to deliver security, comfort and adaptability across environments.
Powering the Oshoro Collection is the regulated and custom-decorated ES-M9015 automatic movement, selected for its proven reliability, accuracy and long-term performance.
Visible through the sapphire case back, the movement reflects Emerton Scott’s commitment to engineering, refinement and enduring craftsmanship.
As part of our commitment to continuous improvement, subtle updates to the Oshoro Collection will be introduced over time to further refine performance and execution.

Our Dial Creation Process
Ocean Inspired
Inspired by the last light of the horizon fading across open water, the Oshoro Dive Watch features a dial shaped by the natural rhythm of the sea. Its surface is created through a layered finishing process that builds subtle depth and texture, evoking the steady movement of ocean waves rather than a static pattern.
As light travels across the dial, it reveals shifting contours and tonal changes that bring a quiet sense of motion, while maintaining full clarity and legibility.
Engineered for true underwater performance, this is a dial designed for a 300m dive watch—calm, functional, and purpose-built, with the ocean embedded in every detail.
Engineered for Depth
Designed Under Pressure
Designed for exploration below the surface, the 300m water resistance gives confidence in environments where pressure becomes part of the experience.
Engineered to perform underwater while remaining refined on land, every detail is shaped for durability, legibility, and reliability—whether timing a descent or wearing it every day.
Surgical 316L Steel
Built from surgical-grade stainless steel, offering superior corrosion resistance and long-term durability. This premium alloy maintains its lustre, resists tarnish and oxidation, and ensures your watch lasts the test of time.
Date Display
The date complication provides a clear indication of the date offering practical information at a glance for everyday use.
300m Water Resistance
Water-resistant to 300 metres, ensuring dependable performance for travel, swimming and everyday use.
120-Click Dive Bezel
The unidirectional dive bezel features a precise 120-click action with crisp feedback, ensuring safe and accurate elapsed-time tracking.
Brilliance in the Dark
Applied Swiss Super-LumiNova ensures lasting legibility. Its crisp blue glow allows the hands to shine clearly through the night without compromising elegance by day.
Parashock Protection™
Carefully engineered to guard your movement against sudden impacts. This helps preserve accuracy and reliability, reflecting Emerton Scott’s pursuit of resilience and precision.
Built to last
High-Grade 316L
Crafted from premium 316L stainless steel, the case offers exceptional durability and resistance to corrosion. Its hypoallergenic qualities make it ideal for everyday wear, while the finely brushed and polished surfaces highlight the watch’s sculpted form. Chosen by leading Swiss houses, 316L is the benchmark for strength and longevity in high-end watchmaking.
Sapphire Crystal
The dial is protected by a sapphire crystal, prized for its clarity and hardness. Graded 9 on the Mohs scale, sapphire is virtually scratch-proof and ensures lasting transparency. Enhanced with precision polishing, it allows the textured dial and applied indices to be admired in every light, preserving a flawless view over time.
Calibre ES-M9075
The ES-M9075 Calibre blends robust Japanese engineering with practical complication. Featuring a true GMT function, it allows independent adjustment of the local hour hand for seamless travel. Beating at 28,800 vibrations per hour with a 40+ hour power reserve, the movement is refined with custom decoration and visible through a sapphire case back—balancing reliability, precision, and purposeful design.
