- Thickness
- 10 mmMeasured from the case back to the top of the glass. The thinner the case, the easier it slides under a shirt cuff.
- Dimensions
- 35 × 45 mmWidth × height of the case. Not sure how it fits your wrist? Compare all collections side by side further down.
- Back
- Screw-down, sealedThe case back screws down onto a seal, which keeps water and dust out.
- Material
- Surgical steelSurgical steel resists corrosion and is kind to the skin. Hardened steel has a treated surface that resists scratches. PVD gold plating is a thin, durable layer bonded to the steel.
- Glass
- Sapphire with anti-reflective coatingSapphire is the hardest watch glass in common use, so keys and everyday knocks will not scratch it. The anti-reflective coating keeps the dial easy to read in sunlight.
- Water Resistance
- 10 ATM, scuba-diving approved5 ATM is fine for hand washing, showers, swimming and snorkeling. 10 ATM is also approved for scuba diving. Never pull out the crown while the watch is wet.
- Movement type
- AutomaticAutomatic means no battery. The watch winds itself from the motion of your wrist.
- Movement
- Miyota 9039 (Japanese)The engine of the watch. Miyota (Japan), ETA and Sellita (Switzerland) build movements used by many established watch brands.
- Accuracy
- -10 ~ +30 sec/dayHow much the watch can gain or lose. Quartz is measured per month or year. An automatic is measured per day, which is normal for a mechanical watch.
- Functions
- Hr, Min, SecHr = hour hand, Min = minute hand, Sec = seconds hand, Date = date window.
- Frequency
- 28 800 vph32 768 Hz: the quartz crystal vibrates 32 768 times per second, which makes quartz very precise. 28 800 vph: the balance wheel beats 8 times per second, which gives the seconds hand its smooth sweep.
- Power Reserve
- 42hHow long the watch keeps running after you take it off. 42 hours means it is still running the next morning.
- Jewels
- 24Tiny synthetic rubies used as bearings where parts turn, to cut friction and wear. A quartz movement needs few or none, an automatic needs many.

Herman Melville’s Words
Inspired by the poet Herman Melville’s words, 'It is better to fail in originality than to succeed in imitation,' we are devoted to a different path—dedicating ourselves exclusively to elegant rectangular timepieces.
We will never design a round watch!

Rectangular watches are not a variation of round design. They are a different design philosophy.
This guide explores the history, geometry, engineering complexity, movement considerations, sizing logic, price tiers, and cultural significance of rectangular watchmaking - structured as a permanent educational resource rather than a buying article.
