Six people, one room above a sail loft
We assemble, regulate, test and service every Middlewatch on the second floor of 212 Commercial Street in Portland, Maine. The windows face the harbor, which is less romantic in February than it sounds.

How a second mate ended up building watches
Every watch takes the same six steps
This is the path every Middlewatch takes, in order. Nothing is outsourced after the parts arrive.
01
Movement check
Maren
Sellita ships movements in trays of 50. Each one goes on the timegrapher in five positions before anything else and is regulated to −2 to +6 seconds a day. About 20 minutes each.
02
Dial and hands
Theo
Theo fits the dial and sets the hands under a loupe. The 12-to-4 arc has to start within half a millimeter of the 12 index, or the dial goes back to the printer.
03
Casing
Theo
Movement into the case, crown fitted, caseback closed with the batch and serial number engraved. Two hours for a Middle 39, a full day for a chronograph.
04
Pressure test
Ruth
An hour at 25 bar, then a condensation test on a hot plate. 14 of our first 1,000 watches failed here and were rebuilt.
05
Second rate check
Maren
Back on the timegrapher. Anything that drifted more than 3 seconds a day since the first check gets opened up again.
06
Packing
Ines
Bracelet sized to the note in your order, sailcloth strap, strap tool and the test card Ruth signed. UPS collects at 3 p.m., so most orders leave the same day.
The crew list
Every watch ships with a card that names who regulated it, who cased it and who tested it.
Founder, regulation

Maren Lindqvist
Second mate on product tankers from 2010 to 2016. Regulates every movement before it’s cased. Still wakes up at 11:45 p.m. most nights.

Fits the dials and hands and cases every watch. Builds the chronographs, a full day each.
