Sector Chronograph 324.442

Price Tier N/A

Graphic and architectural, the Sector dial separates time indications into distinct rings for clarity at a glance. A disciplined 1930s design language—contrast, symmetry, and precision—translated into a modern collectors chronograph. Back in stock in September. This model is now available for pre-order.

Metropolis Verdict

Who this watch is really for

strong data

Best for

Collectors comparing independent dive or sport watches with about 500m of water resistance.

Collectors who want a chronograph from an independent brand rather than the usual big-brand shortlist.

Collectors looking for a cleaner, dress-leaning independent watch rather than another pure sports watch.

Skip if

You want quartz convenience with minimal setting, winding, or service concerns.

Value note: On paper, the spec mix is sensible: mechanical movement, sapphire crystal, and usable water resistance. The value case is strongest if the design language is what you want.
