F-1253 · DIVER
A REAL TOOLWATCH
The F-1253 is manufactured according to the technical requirements of the DIN 8306 relevant for diving watches and made of the best AISI 316L 1.4435 stainless steel. In addition, it has far more technical refinements, which make this watch a real toolwatch. The historical inspiration for this model is provided by the historic port city of Memel, today's Klaipeda.
The F-1253 has a masculine-shaped 41.5 mm case, combined with a distinctive and robust turbine bezel made of stainless steel. All stainless steel elements are finely bead-blasted, the base engraving is raised and satined.
The F-1253 is available in four impressive versions.
You can choose between dials in Prussian blue or anthracite.
A bead-blasted stainless steel bracelet (1.4435 stainless steel) and a rubber strap in the same color as the respective dial are available for both versions. The steel bracelet and the rubber strap are equipped with the FINDEISEN S.V.F. clasp and withstand a tensile force of at least 200 Nm in both parts of the strap in the prescribed test procedure.
FINDEISEN CALIBER FW 4251
The FINDEISEN automatic caliber 4251 was developed in cooperation with the renowned German watch manufacturer DAMASKO. With the construction details used here, this movement can
only be found in the F-1253.
42 hours power reserve
Regulated in 5 positions
In this technical masterpiece, the automatic-unit has been completely redesigned. It is provided with a pawl-winding, which acts as a converter for the rotor rotation. So every little movement of the rotor is used to tension the spring. The so-called bearing-in-bearing principle is used in the new self-winding: the pawl-winding is guided in a ceramic ball bearing on a circular path and is itself mounted in the ceramic full ball bearing.
The manual winding, which can be used via the crown, is also beared on hardened steel discs. All components in the FW 4251 are hardened, wear-free and low-maintenance. To minimize wear, the tungsten rotor was also equipped with a ceramic ball bearing.
A 3-part soft iron cage is used in the housing of the F-1253, which provides additional magnetic shielding. The movement is beared in a special ethylene-propylene-diene rubber (EPDM). This far exceeds the technical standard for shock protection, DIN 8308.
