The SeaQ 1-36-13-01-80-70, seen from the bench

The Glashütte Original SeaQ (ref. 1-36-13-01-80-70) is a contemporary tool watch embodying the manufacturing philosophy of the Dresden manufacture. The stainless steel case measures 43.20 mm with a sunburst dial, applied white gold indices, and a large readable date window. The manual-wound calibre Glashütte Original 36-13 provides five days of power reserve at 21,600 oscillations per hour. Water-resistant to 30 atmospheres with a screw-down crown and scratch-resistant sapphire crystal. The 21 mm lug width ensures compatibility with aftermarket straps.

Frequently asked questions

What is the lug width of the Glashütte Original SeaQ 1-36-13-01-80-70?

The lug width of the Glashütte Original SeaQ 1-36-13-01-80-70 is precisely 21 mm. This dimension represents the design compromise between the 43.20 mm case diameter and the optimal proportional geometry of the construction. To verify the measurement, use a digital calliper positioned between the inner edges of the lugs, perpendicular to the plane of symmetry of the case. The expected value is 20.8–21.2 mm; any deviation beyond these margins indicates abnormal wear of the spring bar or deteriorated lug.

Which strap material is best suited for the Glashütte Original SeaQ?

The ideal strap material depends on the context of use. For formal and business environments, vegetable-tanned alligator leather in black or dark brown is recommended, as it develops a dignified patina over time and coordinates naturally with the cerebral dial and the satin-finished stainless steel case. Shell cordovan in burgundy tones represents the most elegant option for evening occasions. For aquatic or summer environments, FKM (Viton) rubber guarantees absolute durability. NATO straps in cotton-polyester ballistic offer chromatic versatility and tool-free changes.

How do I change the strap on the SeaQ 1-36-13-01-80-70?

Changing the strap on the Glashütte Original SeaQ 1-36-13-01-80-70 is accomplished by removing the spring bars from the case lugs. Position the watch on a soft pad (felt or rubber) with the case facing downward. Use a spring bar tool or a thin, rounded implement to compress the internal spring slightly, leveraging from the opposite side of the case. Extract the spring bar completely and proceed to mount the new strap by reversing the operation. Apply uniform pressure to avoid scratches on the case.

Is the Glashütte Original SeaQ compatible with aftermarket 21 mm straps?

Yes, the Glashütte Original SeaQ 1-36-13-01-80-70 is fully compatible with aftermarket 21 mm straps. MilanoStraps offers a specialised selection of straps in alligator, shell cordovan, vegetable calf, NATO, and rubber, all certified for this lug width. It is recommended to verify the strap thickness (typically 1.4–1.6 mm for leathers) and total length (usually 110 mm rear section to fit average wrists) before ordering.

What is the average lifespan of a leather strap on the SeaQ?

A quality leather strap (vegetable-tanned alligator or shell cordovan) mounted on a Glashütte Original SeaQ has an average lifespan of 3–5 years with daily use, provided regular maintenance: avoid prolonged exposure to moisture and perspiration, clean monthly with a soft slightly damp cloth, and apply a leather conditioner every 6–12 months. Vegetable-tanned fibres deteriorate more rapidly than cordovan and require rotation with other straps to extend longevity. FKM rubber straps have a lifespan exceeding 7–10 years with the same care.
