It is powered by the ETA G10.212 AB ND quartz movement with hour, minute, small second and split-second chronograph functions. The case features 20mm lugs and uses innovative materials in its construction.

Frequently asked questions

What is the lug width of the Swatch MoonSwatch SO33B700?

The Swatch MoonSwatch SO33B700 features a lug width of 20 millimetres. This measurement is the standard for aftermarket straps compatible with the model, allowing access to a vast selection of leather, rubber, NATO, and metal options available in the specialist market.

What is the best strap for the MoonSwatch SO33B700?

Strap selection depends on intended use. For an elegant-casual approach, we recommend natural alligator with vegetable tanning in brown tones; for an urban-sporty style, vegetable-tanned calf leather in grey with contrast stitching; for maximum daily practicality, black FKM rubber with stainless steel deployante. Each material highlights different aspects of the Bioceramic case.

How do I change the strap on the MoonSwatch SO33B700?

Removing the SO33B700 strap is straightforward: use a spring bar tool and gently push it inward to extract the elastic pin from one of the two lugs. Once the pin is removed from a single lug, the strap slides away. For installation, insert the pin into the new strap and push until you feel the catch click on both sides.

Are there aftermarket straps compatible with the MoonSwatch SO33B700?

Yes, the SO33B700 is fully compatible with any quality 20mm strap produced by specialist craftsmen. Being an international standard, you will find options in leather (alligator, calf, shell cordovan), rubber, NATO fabric, and even metal, without brand restrictions.

How long does a leather strap last on the MoonSwatch SO33B700?

The lifespan of a leather strap varies depending on material quality and usage conditions. A quality alligator or vegetable-tanned calf typically lasts 3–5 years with regular maintenance (occasional cleaning, water protection); shell cordovan can exceed 7–10 years. Primary wear concentrates on the buckle closure area and flexion points from daily wear.
