Frequently asked questions

What is the lug width of the Omega Seamaster Planet Ocean 2900.50.37?

The lug width of the Seamaster Planet Ocean 2900.50.37 is 22mm. This width is the specific standard for this model and is calculated to maintain correct proportions on the 45.5mm case. Always verify by measuring the distance between the lug pins before purchasing a compatible strap.

What strap material do you recommend for the Seamaster Planet Ocean 2900.50.37?

For the Planet Ocean 2900.50.37 we recommend vegetable-tanned alligator (natural scaled texture and evolved patina), shell cordovan (superior density and lasting lustre), or vegetable-tanned calf leather for softness and sobriety. For sports use or humid environments, natural rubber or tactical NATO nylon are optimal choices.

How do I change the strap on my Seamaster Planet Ocean 2900.50.37?

The strap on the Planet Ocean 2900.50.37 is changed by extracting the lug pins with a dedicated tool (spring bar remover). Position the watch on a soft surface, locate the small lateral slot on the pin, insert the tool and gently push until the old strap is released. Insert the pins into the new 22mm strap until they click. We recommend having a professional watchmaker assist you the first time.

How long does a leather strap last on the Seamaster Planet Ocean?

A quality leather strap (alligator, shell cordovan or vegetable-tanned calf) on the Seamaster Planet Ocean lasts on average 3-5 years with daily use, depending on exposure to humidity, sweat and sunlight.
