Stepping up in the same dial colour
The Conquest name has been registered Swiss intellectual property since 1954 — longer than most watch families have existed — and this 30mm quartz version carries that continuity without making a fuss about it. The line sits distinct from the dive-oriented HydroConquest and the dress-leaning Conquest Classic, occupying the middle ground: capable, presentable, and built to wear without thinking about it. At 30mm the case is compact enough to sit neatly on a narrower wrist, and 8.3mm of thickness keeps it from riding high under a cuff. The combination of stainless steel and yellow gold PVD runs through the case, bezel, hands, indexes and bracelet consistently, so nothing looks borrowed from a different watch. The white sandblasted dial diffuses light rather than reflecting it, which means the gold-coloured hour markers read cleanly across changing conditions. Date at six o'clock is placed where it interrupts nothing. For a watch rated to 100 metres, the folding clasp with triple safety is correct rather than cautious.

Learn more about Longines
Auguste Agassiz began trading watches in Saint-Imier in 1832, but the modern company dates from 1860, when his nephew Ernest Francillon built a factory in the meadows beside the Suze — the longines of the local dialect — and consolidated the scattered outworkers of the region under one roof.
Longines registered its winged hourglass in 1889. It is the oldest watch trademark still in continuous use.
The company's identity was built on precision and on timing things in public. It supplied chronographs for the first modern Olympic events it timed in 1896, timed the 1912 Federal Gymnastics Festival with a broken-wire mechanism accurate to a hundredth of a second, and developed the photo-finish camera and the quartz timing devices used across twentieth-century athletics.
Its aviation associations are equally deep. Longines instruments were carried by Charles Lindbergh across the Atlantic in 1927, and the Hour Angle watch, designed to Lindbergh's own specification to simplify longitude calculation, remains in the catalogue. Amelia Earhart and Howard Hughes both navigated by Longines.
The house was among the most decorated at nineteenth-century observatory trials, holding numerous precision records. Since joining the Swatch Group in 1983 it has occupied the accessible-heritage position: exclusive ETA-based movements, archive-driven designs through the Heritage line, and volume that makes it one of the group's most important brands.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Yes. At 100m it is rated for swimming and snorkelling, though not for diving.
Water resistance explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes it need a battery?
Yes. It is quartz, so expect a battery change every two to three years at a jeweller.
Quartz, automatic and solar comparedIs it a men's or women's watch?
Listed as women's.
