The Hublot Big Bang Automatic is a stylish mens' chronograph watch featuring a 44mm round case crafted from stainless steel with distinctive lateral black Kevlar inserts and equipped with a fixed bezel also in stainless steel. It comes fitted with a black rubber strap measuring 25mm in width. The dial displays an analog design, rendered entirely in black, accented by luminescent silver-tone skeleton hands that are designed to look like they are made of a lighter material (silver-tone), and features alternating Arabic numeral hour markers at positions 3,6,9,12 combined with luminous index minute markers. The outer rim also has minute markers for precise analog reading.
This watch includes all the functions: chronograph, date display positioned between 4 and 5 o'clock, telling of hours, minutes, and seconds. The main complication is its integrated three-register sub-dial chronograph system displaying elapsed time in 12-hour format (a smaller one at 9 o'clock), elapsed minutes up to 30 minutes (at 6 o'clock) on a large central disc, and small seconds for the chronograph function located near the 12 o'clock position. Other features include: scratch-resistant sapphire crystal lens protecting the black dial; pull/push crown operation for functions like chronograph start/stop/reset; transparent case back revealing the automatic movement inside; water resistance to a depth of 100 meters or 330 feet, suitable for recreational swimming.
Powering this Hublot timepiece is its proprietary calibre HUB4100 automatic movement. This mechanical heart draws inspiration from ETA base movements (ETA 2894-2) but boasts higher specifications: it incorporates 27 jewels and is composed of over 252 individual parts, ensuring precision with a vibration frequency of 28,800 vph (or beats per hour). The movement provides approximately 42 hours of continuous power reserve when fully wound. It represents the Hublot Big Bang Automatic style, a blend of sporty chronograph elements and refined dress watch aesthetics.
