Massive Indicator World Clock turns open wall space into a functional clock feature without adding visual noise. Massive Indicator World Clock from Grandmix is a coordinated set of 3 or 4 silent quartz clocks with engraved city name plates beneath each clock, each timezone tracked independently, no audible ticking, lobby-ready out of the box. Available in 3-city (180 cm wall span) or 4-city (240 cm wall span) configurations and 3 finishes (Matte Gold, Black, Brushed Nickel). Why It Works Independent silent quartz movement per clock: Unlike single-clock displays that show only one timezone or budget multi-clock kits with audible ticking, each clock in this set runs a separate silent quartz movement, set each to its own time zone, with no synchronization wiring and no ticking through the lobby. Engraved metal city plates beneath each clock: Unlike printed labels or laminated decals that fade with wall washing, the engraved metal plates beneath each clock give the wall the finished, custom feel of permanent hospitality signage. 3-city or 4-city configurations: 3-city covers 180 cm of wall span (3 clocks at 60 cm each, with spacing); 4-city covers 240 cm. Both fit standard hotel lobby walls, executive office focal walls, and international corporate spaces. Designed in-house at Grandmix's Türkiye studio: Drawn and prototyped for considered hospitality craftsmanship and a more intentional lobby presence.

Mark mounting points evenly spaced across the layout, drill pilot holes, insert the included wall anchors, and drive the mounting screws. Insert one AA battery per clock and set each clock independently to its time zone using the back-mounted adjustment knob. Mount the engraved city plates beneath each clock using the included plate hardware. Total install for the full set takes 30-45 minutes for the 3-city configuration and 45-60 minutes for the 4-city configuration; a level and a second set of hands help with alignment. Care Wipe each frame, indicator dial, and engraved city plate with a soft, dry cloth to remove dust. Clean glass faces with a non-abrasive glass cleaner; avoid abrasive cleaners or chemical solvents on the powder-coat finish. The clocks are designed for indoor use; avoid prolonged direct sunlight, which can dull powder-coat finishes over time. Frequently Asked Questions Do the clocks tick? Are they audible in a lobby? No. Each clock runs an independent silent quartz movement that advances the second hand smoothly without the audible tick of traditional quartz or weight-driven clocks. Suitable for lobbies, executive offices, libraries, and other spaces where ambient quiet matters to the guest experience. What batteries do the clocks take, and how long do they last? Each clock runs on one AA battery, none of which are included. Fresh alkaline AAs typically power each movement for 12–18 months under normal indoor conditions, while lithium AAs may last longer. Replace batteries annually across the set for consistent timekeeping. Can I customize which cities appear on the engraved plates? Yes. Specify your chosen cities at order for engraving on the included metal plates (3 cities for the 3-city configuration, 4 cities for the 4-city configuration). For bulk hospitality orders or custom plate engraving beyond standard cities, contact Grandmix directly for custom-order options. What walls and hardware does the set work with? Each clock uses an integrated back hook, and mounting screws and anchors are included for each. Choose anchors rated for your wall material; for masonry or concrete lobby walls, use masonry-rated anchors. Plan the wall span (180 cm for 3-city, 240 cm for 4-city) before drilling. How do I clean the clocks and city plates? Wipe the powder-coated frames, brushed metal dials, and engraved city plates with a soft, dry cloth or microfiber to remove dust. For glass faces, use a non-abrasive glass cleaner sprayed on a cloth (not directly on the glass) and wipe gently; avoid abrasive cleaners or chemical solvents that can dull the powder-coat or engraved finish.
