AIS BronzePen

BronzePen

The AIS BronzePen is a gentle yet highly effective solution for maintaining bronze watches. Developed in Switzerland specifically for bronze cases and bracelets, it reliably removes unwanted patina without damaging the original surface or the character of the metal. Thanks to its soft brush head, it can easily reach even hard-to-access areas, ensuring even cleaning of the entire case and bracelet. The pen's design is practical, compact, and ready for immediate use—just open, apply, and gently brush. Furthermore, its long-lasting performance of up to 60 applications makes it a reliable tool for the regular maintenance of your bronze watches.

The package also includes a 30x30 cm polishing cloth (white side for drying and black side for polishing) made from 100% natural cotton, extra thick for maximum absorption.

WARNING: Before use, check that your watch is waterproof, and note that the BronzePen is not suitable for leather straps. For the treatment of leather straps, we recommend the ChronoLeatherPen product from our range.

How to Use

• How to use

  1. Ensure the watch crown is tightened, and if the watch has a leather strap—remove it. For bronze bracelets, use is fine.

  2. Hold the BronzePen with the brush head facing upwards, remove the cap, and press several times until the emulsion reaches the bristles.

  3. Gently move the brush in circular motions over the surface of the case and bracelet, focusing especially on patinated or tarnished areas. For a more pronounced result, brush longer; for a gentle refresh of the patina, brush for a shorter time.

  4. After cleaning, rinse the watch in lukewarm clean water, dry with a soft and clean cloth. Rinse the BronzePen brush under running water.

  5. For a final shine, we recommend using a polishing cloth (e.g., brushed microfiber), ideally a cloth from the same brand.

  Tip: If you want to retain some of the patina and preserve the watch's character—stop cleaning earlier and rinse. For a clean, "like new" surface—brush a little longer.
