The 8421 does not hide. A round alloy case, 47 mm across and 14 mm thick, 153 g on the wrist — big, legible, built for someone who does not want to hunt for the time. The strap is silicone: comfortable across a full day and easy to rinse off when the job gets dirty. A quartz movement runs it, so there is nothing to wind and nothing to fuss with. Set it and it keeps going.
The dial carries a calendar, three sub-dials and luminous hands — the part you appreciate when the shift starts before sunrise. On water we will be plain about it: this one handles splashes and rain, and it is not for swimming, showering or diving. Made in Guangdong, China, and sold here for around COP $130,000 in black, blue, green, yellow and grey. That is daily-wear money, not display-case money.
Water resistance 3 ATM: splashes and rain. Not for swimming or the shower.
Origin: Guangdong, China.
