The SeaQ Panorama Date (ref. 1-36-13-01-81-71) is Glashütte Original's modern dive watch, 43.2mm steel, 300m water resistance, the in-house caliber 36-13 with the brand's panorama big-date at four, and dial-design language traced directly to the 1969 Spezimatic Type RP TS 200 the GDR-era Glashütte workshops produced for the East German domestic market. It is one of the few haute-tier German dive watches in the catalog and the brand's most direct claim to sport-watch credibility.

What it is

The original Spezimatic Type RP TS 200 was a 1969 dive watch produced by VEB Glashütter Uhrenbetriebe, the East German watchmaking combine that controlled the Glashütte workshops between 1951 and 1990. The 200m water-resistance figure was unusual for the period and the design (cushion case, oversized minute markers, sword hands) became a small cult reference among GDR-era collectors. Glashütte Original revived the line in 2019 as the SeaQ; the Panorama Date generation added the brand's signature big-date complication and the in-house caliber 36-13 with 100-hour reserve.

The 39.5mm (no-date) and 43.2mm (Panorama Date) variants both ship; the larger reference is the family's commercial center.

Buying notes

Common things to check: bezel insert (the SeaQ uses a ceramic insert with 60-click bidirectional ratcheting on the no-date variant and unidirectional on the dive-certified Panorama Date, verify directionality matches the reference); papers and the brand's chronometer certificate (the caliber 36-family chronometer card should accompany the watch); helium-escape valve (the SeaQ is rated to 300m but does not include a helium-escape valve, divers should not confuse it with saturation-rated references); strap/bracelet (the watch ships with quick-release straps and the brand's signature steel bracelet, confirm which is included against the box contents); caliber 36-13 (verify the free-sprung balance and the panorama date alignment through the case-back).

Market read

Steel SeaQ Panorama Date examples trade in the $9,000-$12,500 range through 2025-2026, against a current retail of approximately $13,500. The reference is one of the catalog's quieter sport-watch positions. Glashütte Original has not pursued the sport-watch market with the marketing intensity that drove the Submariner / Aquatimer / Royal Oak premiums, and pricing has been steadier as a result.

Cross-shopped against the Blancpain Bathyscaphe or the Tudor Pelagos, the SeaQ sits in the middle of the spectrum and offers in-house finishing the Sellita-based competitors do not match.

Service expectations

Service is Glashütte Original-direct. Expect 4-8 month turnaround and a low-four-figure service bill. The caliber 36-13's date module adds modest complexity to the service workflow but is well-understood by the brand's service department.

Water-resistance testing is part of every factory service; an example that has not been pressure-tested in 5+ years should not be used for actual diving without service first.

Authentication

Panorama date on a professional dive case; unidirectional bezel counterclockwise only and gasketed caseback confirm dive specification.

Known issues in the market

Bidirectional bezel compromises diver safety function; bezel must only ratchet counterclockwise.
Caseback gasket condition determines water resistance; verify gasket is intact before water exposure.

Authentication guide

Last reviewed June 2026

The SeaQ Panorama Date is an unusual combination: GO's traditionally refined movement inside a 43.2mm dive case with 300m water resistance and a ceramic bezel. The panorama date appears at 6 o'clock on this model, not the standard 12-to-1 zone. This positional difference from the rest of the Pano family is the primary dial-level identity check.

Known reproduction risks

toggle

MEDIUM

The SeaQ is an unusual piece that is rarely replicated. The ceramic bezel scratch test and the panorama date position at 6 o'clock are the two fastest checks.

Date aperture at upper right instead of 6 o'clock (wrong movement variant)
Bezel that accepts key scratches (not ceramic)
Three-quarter plate absent through caseback
Case proportions inconsistent with the 43.2mm SeaQ specification

Ceramic bezel

Original: Unidirectional ceramic dive bezel with correct 60-minute scale. Ceramic is scratch-resistant: a key will not mark it. The click stops engage firmly at each position.

Replacement tells

Bezel surface that accepts key scratches (ceramic does not; aluminum does)
Bidirectional bezel rotation on a stated SeaQ (the bezel should be unidirectional)
Click stops that slip rather than engaging with positive resistance

Panorama date at 6 o'clock

Original: Two stacked discs at the 6 o'clock position. This placement is specific to the SeaQ and differs from the rest of the GO Pano family. Both discs should jump simultaneously at midnight.

Replacement tells

Date aperture at the upper right (12-to-1 zone) rather than at 6 o'clock -- a standard Pano movement in the SeaQ case
Date that advances in multiple steps rather than jumping
Disc vertical misalignment at the aperture

Movement via caseback

Original: Exhibition caseback displaying Cal. 36-13. The three-quarter plate with Glashütte ribbing is visible. The same finishing standard as other GO calibers applies.

Replacement tells

Three-quarter plate absent
Glashütte ribbing without flat-polish character between grooves
Movement layout inconsistent with Cal. 36-13 architecture

Case back markings

toggle

2020 to present

Exhibition caseback displaying Cal. 36-13
Three-quarter plate with Glashütte ribbing visible
"Glashütte Original" and "Made in Germany" on the movement
"300m" water resistance on the caseback
Reference and serial number on the case band
Steel hallmark

Movement tells

toggle

Cal. 36-13 is the SeaQ-specific adaptation with the panorama date output at 6 o'clock. A non-SeaQ GO Pano movement (with date at upper right) in a SeaQ case is an unauthorized parts combination.
Three-quarter plate finishing is the primary movement tell: Glashütte ribbing must be perfectly parallel with flat-polished inter-groove lands under magnification.
Power reserve is approximately 42 hours. A SeaQ Panorama Date stopping before 35 hours when fully wound warrants service.
Water resistance of 300m should be confirmed after any service event. The screw-down crown and case seal must be tested before returning the watch to dive use.
