Full Specification
Case
- Fully machined in-house from a billet of lightweight structural grade 6082 T6 alloy, offering high strength and excellent corrosion resistance. Lightly finished by hand, retaining some machining marks.
- Solid uni-body monocoque construction.
- 41mm case size (measured diagonally, excluding crown).
- 11mm case thickness (excluding crystal).
- 48mm lug-to-lug measurement, suited to all wrist sizes.
- Integral solid fixed strap bars for ultimate strength when used with “single-pass” and NATO style straps.
- Screw-down stainless steel crown, positioned at two o’clock for comfort wear during wrist articulation.
- Deep engraved case-back, individually serialised.
Dial
- Fully machined in-house from 6082-T6 aluminium alloy (for silver dials), or CZ121 brass alloy (for gold SULIEN "sun-born" dials). Finished by hand.
- Unique design with hexagonal markers and radially tapered indices at 3, 6, and 9 o'clock positions.
- Deep engraved and hand-filled enamel markers.
- Date window positioned between 3 and 4 o’clock markers. Also available without a date for those that prefer a cleaner dial.
Hands
- Hour, minute, and sweeping second hands.
- All hands applied with non-radioactive alkaline rare earth metal phosphorescent “lume” (silicate-aluminate oxide, doped with europium ions).
- The design of the second hand differs slightly, depending whether a Swiss or Japanese movement is chosen. The Swiss movement uses a second hand without the "arrow" at the tip.
Crystal
- “High-domed” for easy viewing at acute angles.
- Shatter resistant acrylic.
- Optical quality.

Box
- Each Model 525 is supplied in its own rugged travel case, incorporating a hard crush-proof ABS (Acrylonitrile Butadiene Styrene) textured outer shell, with a soft shock absorbent foam liner.
- Includes signed guarantee card with guarantee information, inspection record, and digital operation instructions.
- Also in the box you will find a small glass vial filled with some of the machining swarf from the production of your actual watch, which makes for a unique memento, emphasising the craftsmanship and in-house manufacturing process behind your watch.
Care Notes
- While the material used for the case is tough and strong, it can pick up scratches and dents with use. We believe that the material chosen offers excellent properties of strength while remaining lightweight and comfortable to wear. Case polishing wool (available on the accessories page of the website) can be used to remove light scratches. We build our watches to be worn and enjoyed, and believe that every scratch tells a story!
- Acrylic crystals are incredibly strong and shatter resistant. However, they can pick up scratches with use. It is relatively easy to polish out scratches using Polywatch (available on the accessories page of the website) and a soft cloth, if you wish.
- Every watch is vacuum leak tested to -760mm of mercury, which is equivalent to 1 bar, or 10 meters (33 feet) of water pressure resistance. This level of test is suitable for exposure to handwashing and rain, but we do not guarantee or recommend full submersion i.e. swimming.
