Cheap Casio Mod — I Turned a Casio A158 Into a Black Gem

I took a humble Casio A158 and turned it into ONYX — a custom watch inspired by the deep, polished black of onyx stone. Starting with a rough A158, every detail was carefully reworked to create a darker, cleaner, more refined version of the original. This is the making of ONYX. 🛒 Online Store & Socials • Etsy / Shop: https://www.etsy.com/shop/SUIKAandKYURI • Instagram:   / suika_and_kyuri   ⏱️ Timestamps 00:00 Intro 00:22 MOD CONCEPT 01:20 THE DIAL 01:56 THE CASE 02:51 THE LEDS 03:33 WRAP-UP ⌚ Watch Details Model: ONYX Base Model: Casio A158 SUIKA & KYURI BUILDING THE BEST CUSTOM CASIOS IN TOKYO. #f91 #casio #casiomod #a158 #casioa158 #watchmod #customwatch #watches #watchmaking
