Frequently asked questions<\/h3>\n
Can it be used for real diving?<\/summary>\n

The stated water resistance is 30 ATM (300 m). The decompression bezel is the model's signature, not the tool you plan a dive with: for that you use a dive computer.<\/p>\n<\/details>\n

How long does it run if I don't wear it?<\/summary>\n

About 38 hours. Left still beyond that it stops: wind it from the crown or put it back on.<\/p>\n<\/details>\n

Why is the dial that color?<\/summary>\n

DOXA dial names are a house language: Professional is the orange born in 1967 because underwater it is the color you can read longest, Sharkhunter black, Searambler silver, Divingstar yellow, Caribbean blue.<\/p>\n<\/details>\n

Can I change the strap?<\/summary>\n

Yes: the lug width is 20 mm, so any strap or bracelet in that size fits. We fit it for you in the shop.<\/p>\n<\/details>\n

Do you ship to the United States?<\/summary>\n

Yes, worldwide, insured and tracked. For a delivery outside the European Union the Italian VAT is removed at checkout; duty and import tax in the destination country are the buyer's.<\/p>\n<\/details>\n

What warranty does it carry?<\/summary>\n

The DOXA international warranty, with the certificate filled in and stamped by us: Cicala Gioiellerie is an authorised DOXA retailer.<\/p>\n<\/details>","protected":false},"excerpt":{"rendered":"
