The Coastal by Golby Watches - Video Review
The Coastal and a Brief History of Golby Watches
"Golby Watches is a husband-and-wife duo, Craig and Sarah. Based in Solihull. Starting life in 2021, they focused on bringing affordable but stylish straps and accessories to the market. Successfully launching their first watch in 2024, The Aquareef. The Golby aesthetic is inspired by the British coastline. Integrating these influences into gender-neutral designs that are vibrant, accessible and pragmatic. The Coastal was born out of the desire to create a practical tool watch with all the functionality of a diver’s watch but built into a compact package, with the Golby DNA running throughout.
Featuring Golby’s trademark oil-pressed dial in rich colourways with calm undulating waves, which catch and dance in the light. Angled chapter ring and minute markers. The Sapphire glass bezel insert, with BGW9 Super-Luminova and countdown markers, a practical tool for everyday life, with a bold contrasting last quarter on 5 of the 7 colourways, to mark those final 15 minutes.
A new feature to the Golby collection is its’ custom lighthouse hands and markers at 3, 6, 9 and 12, a further nod to its coastal inspiration, guiding people safely home into the harbour. They are finished in a highly polished stainless steel and with BGW9 Super-Luminova adding dimension to the overall effect. The Coastal has a custom 36mm, 316L stainless steel case under a 37.4mm bezel. Offering an understated but practical grip. The watch measures 10.7mm thick and 44mm lug to lug. With practicality in mind the case has a brushed finish, ready to stand up to your adventures and fit for daily wear. Elongated by the polished chamfered edge, creating contrast and a purposeful interruption to the flow. Responding to feedback they have an updated logo design applied to the textured dial and a more simplified format also found on the screw-down crown and bracelet.
Golby have designed a brushed 304L stainless steel 5-link bracelet with butterfly clasp. Starting at a 20mm lug fitting, that tapers to 18mm at the clasp. It incorporates female end links, two half links and quick release spring bars. Allowing for 12 split pin links to be easily removed. This will ensure maximum flexibility for all wrist sizes, offering a sleek, snug fit. The versatile 20mm lug width ensures it can be swapped easily to any of your other straps, of which Golby Watches stock many options in their online store. The Coastal is tested to 20ATM (200 meters) making it the perfect timepiece for your water adventures, for swimming and diving with confidence. Featuring a flat sapphire crystal and 5 layers of anti-reflective coating, offering the practicality of being scratch resistance and unparalleled clarity, providing a clear view of the dial from every angle.
The Coastal houses a Miyota 90S5 movement with 42+ hour power reserve and regulated to -10/+30 seconds per day accuracy. Part of the Miyota 9 series, the 90S5 is a premium automatic/self-winding movement, known for being compact, reliable and robust, perfect for any tool or divers watch. The no-date movement is only 3.90mm thick, has a uni-directional rotor, 28,800bph and hacking functionality. The watch holds a hidden personal touch, with original line artwork engraved into the solid case back, produced by their niece Caitlyn. Golby Watches really is a family affair."
