Odyssey Founder Pre-Order

THE ODYSSEY

BUILT FOR EVERYTHING.

A purpose-built automatic tool watch designed to go wherever life takes you. The case, dial, bezel, and hour and minute hands weren't picked from a parts catalog — they're original designs, drawn and engineered specifically for Tertia.

Designed from scratch

The case geometry, dial layout, bezel, bezel insert, and the hour and minute hands were designed from a blank page specifically for Tertia — not selected from an existing catalog. Each one went through multiple rounds of drawings and revisions before becoming what you see now.

The seconds hand is the one component sourced rather than drawn in-house.

About Tertia

Tertia is an independent, owner-operated watch company based in Virginia. I handle the decisions that take the Odyssey from a sketch to a finished watch — the design, specifications, and the final quality control before it ships.

The design work you just read about is mine as well. Every sketch, revision, and final line on the case, dial, bezel, and hands passed through me directly, from first draft to production.

If you have questions at any point, you're reaching me directly, not a support queue.

Final assembly, regulation, QC in the USA

Full manufacturing in the USA wasn't possible at this price point. Rather than compromise the watch itself, every Odyssey goes through final assembly, movement regulation, and quality control in the United States, working with other American businesses wherever possible in the process.

The Odyssey

The design choices weren't made to look a certain way — they were made to hold up. A watch intended to go wherever you do needs to handle water, impact, and daily wear without asking you to baby it.

That standard is what shaped every spec below. When you put it on, the reaction should be simple: this makes sense.

Founder pre-order

The first production run of the Tertia Odyssey is being offered through Founder Pre-Order and is limited to 100 watches.

Founder Pricing: $895 USD Free U.S. shipping · Taxes calculated at checkout

This run size isn't a marketing number — it reflects a supply constraint on the Miyota 9000-series movement. Rather than delay the whole run waiting on additional movements, production was limited to 100 so the watches already ordered stay on schedule.

Founder Pricing does not represent a different version of the watch. Every Odyssey is built to the same specifications and quality standards.
