Isotope GMT 0º ‘Terra Maris’

Isotope Watches is introducing a limited edition of its GMT 0º ‘Terra Maris’ in collaboration with Miguel Seabra.

Introducing the Isotope GMT 0º ‘Terra Maris’

The GMT 0º ‘Terra Maris’ Limited Edition, is produced in collaboration with Miguel Seabra — one of the most experienced and iconic journalists of the watch (and tennis!) scene.

The GMT 0º ‘Terra Maris’ is a limited run of 49 pieces and features a unique GMT + date display, and an original colour combination inspired by the seaside. Here’s Miguel Seabra’s rationale behind the creation of the ‘Terra Maris’ concept:

“When my friend José Mendes Miranda, founder of Isotope Watches, challenged
me to come up with an idea for a limited edition of the GMT 0º, I pretty much
envisioned a theme straight away since it had been on the back of my mind for a
while. If I were to be associated with a timepiece, it would have to be quite different
and boast an original colour combination. And… cool as well! So, being the GMT
0º a travel watch per definition, and being Isotope a watch brand based in a country
(England) with the same time zone as mine (Portugal), I wanted it to reflect a bit the
beautiful place where I live on the seaside and not only convey the idea of vacations
but also casual elegance. To me, the epitome of casual elegance is a good pair of
jeans coupled with brown suede shoes plus a white shirt and a nice blazer. Brown
and blue also represent the land and the sea, and I live in the coastal resort
of Cascais, at the most western point of Europe, where the continent ends and the
ocean starts. Hence the Latin name, ‘Terra Maris’. The land and the sea, the brown
and the blue, suede shoes and denim!”.

“I am also proud to collaborate with a microbrand as offbeat as Isotope Watches.
Microbrands have been doing a terrific job allowing easier access to the not so
cheap world of mechanical watchmaking and/or providing a choice to those who
prefer wearing something out of the box. The Isotope GMT 0º is an original
timepiece, with its never before used combination of a GMT disc with a date
displayed via a black dot shifting around the 31 holes on the dial. That also makes it
a talking piece, a conversation starter. So, if ever you get stuck with strangers on a
lift, you can always use it to unblock uncomfortable silences”.

“Another good point for a travel watch suited for summer destinations is the water
resistance; the GMT 0º ‘Terra Maris’ is water-resistant to 200 meters due to its thick
3mm sapphire glass and screwed crown. It is robust enough to go dive with and
wear on the beach. A reliable Swiss Landeron automatic movement makes it ready
to go and wear anywhere, anytime”.

“Of course, being a strapaholic myself, the GMT 0º ‘Terra Maris’ had to come with
two choices: a metal bracelet with a clasp featuring three adjustment positions and a
brown retro leather strap with blue stitching; but a black strap also works very well,
matching the black tip of the ‘Lacrima’ on the centre of the dial, whereas a white or
light blue strap would reinforce the holiday/summer aura of the watch”.

“Two small details also make this limited-edition special compared to other GMT
0º models: the ‘Terra Maris’ nomenclature is discreetly engraved on the central GMT
disc, whereas on the back the GMT zone indicated is Lisbon (not London). A third
asset is the luminescence on the hour markers beside the hour/minute hands and
GMT dot, which doesn’t happen in the regular GMT 0º pieces of the collection”.
“The GMT 0º ‘Terra Maris’ edition is limited to 49 individually numbered pieces.
Why such an odd figure? Because ‘my number’ is Thirteen; only 13 watches would
not be enough and 130 would be too many. But 4+9 equals 13; I hope it’ll be a lucky
number for everyone who chooses to have one!”
